Pi Mu Epsilon

Pi Mu Epsilon, a national honorary mathematics society, was founded in 1914 at Syracuse University and was incorporated on May 25, 1914, under the laws of the State of New York. Its roots date back to a mathematics club that was founded at Syracuse in 1903. Pi Mu Epsilon (PME) is a non-secret organization whose purpose is the promotion of scholarly activity in mathematics among students in academic institutions. You can find out more information about the national organization by visiting the PME National Website.

We maintain an active chapter of Pi Mu Epsilon here at Ole Miss and induct new members each year. We meet approximately three times per semester for activities or an informal math presentation. Presentations are usually made by undergraduate students, graduate students, and faculty. Sometimes we have speakers present about career opportunities for those who are majoring in mathematics and STEM related fields.

You may join the national organization without attending the local meetings, or you may simply attend the local meetings without joining the national organization. Of course, we hope that you do both.

Connect the Dots! Maximal Polygons on a Square Grid (pdf)
Given an n × n grid of dots, can you connect all of the dots and end up with an n2-sided polygon? If n=2, it’s easy. If n=3, it’s impossible. What about for larger values of n? We’ll explore this problem together and work out exactly when such a polygon exists.

Integer Partitions (pdf)
An integer partition of n is a non-increasing sequence of positive integers whose sum is equal to n. For example there are 5 partitions of 4:
4, 3+1, 2+2, 2+1+1, 1+1+1+1
This simple definition is the seed of a deep mathematical theory that spans number theory, combinatorics, and analysis, dating back centuries. We will explore the patterns and relations that can be found among partitions and discuss some open problems that have mystified mathematicians for generations.

Solving the 15-Puzzle (pdf)
The 15-Puzzle is a sliding puzzle where the goal is to arrange the pieces in order from 1 to 15 with the empty space in the bottom right corner. In 1891, puzzle maker Sam Loyd offered $1000 to anyone who could solve the puzzle above with only pieces 14 and 15 switched. Nobody ever claimed the prize. We will discuss the reason that this challenge remains unsolved using modern algebra techniques and provide an algorithm to solve the puzzle given different arrangements of the pieces.

Prime Numbers (pdf)
This informal discussion will be about one of the most important sequences of numbers {2, 3, 5, 7, 11, 13, 17, 19,….}, the set of prime numbers. Learn about classic works of Euclid and Gauss, and how their ideas have inspired the deepest works by contemporary mathematicians such as Ben Green, James Maynard, and Fields medalist Terry Tao. The deepest of these works is now so well understood that the proofs are accessible to advanced undergraduates. In fact, these results have been refined in various ways in the speaker’s REU summer programs.

Finding Hay in a Haystack (pdf)
Existence results are ubiquitous in mathematics. Proving that something exists does not necessarily provide a method to find it. Stranger still, in many situations one can prove that a certain property is satisfied by many (or even most) objects, yet it is very difficult to find a single object satisfying the property. I will take you on a tour and show you examples of this nature in different areas of mathematics such as set theory, analysis, number theory and combinatorics.

Uncovering Hidden Variables (pdf)
In latent-variable models, the distributions of observed random variables depend on underlying, unobserved variables. Because these models allow for the possibility that hidden forces shape the observable world, they have many applications in the social and physical sciences. I will discuss when, and how, the relationships between observed and unobserved random variables can be recovered from variation in observed variables. I will also introduce a computational technique for estimating latent-variable models from sample data.

The Isoperimetric Problem (pdf)
Among all closed, non-intersecting curves of the same length on the plane, which curve encloses the largest area? This question is known as the isoperimetric problem. While the answer, a circle, has been known since antiquity, this problem was only studied rigorously in the 19th century. I will talk about the history of this problem and its influence on modern mathematics.

Automating the Hilbert-Kunz Multiplicity and F-Signature (pdf)
We will discuss an automation of a calculation in Algebra arising from current research. The computation, which finds the volume of certain polytopes, is tedious and time-consuming to do by hand, but perfectly suited for computer programming. We begin by presenting the background of the automation and then see it in action. This work is part of a joint research project with Gabriel Johnson, who earned a BS in Computer Science through the Barksdale Honors College in 2018.

Estimation of Pi by Statistical Methods (pdf)
Pi is probably the most recognized mathematical constant in the world. In this talk, I will begin by discussing some interesting facts about Pi and reviewing the history of Pi approximation. Then, after a brief introduction of statistical concepts, I will present two statistical techniques for estimating Pi, called respectively the point and interval methods. To demonstrate these contrasting methods, I will show simulations generated through the statistical software R.

Actuary 101: The Math of Pricing Unpredictable, Destructive Events (pdf)
We know that unpredictable, financially-destructive events will occur… to someone… somewhere. At a fundamental level, insurance is a financial strategy by which a group of people can pool an individually small portion of their resources to redistribute them in the future to those in the group who become victims of costly misfortunate events. But how much should individuals in the group pay to ensure that this program is likely to be solvent? It is the work of an actuary to analyze real-world data and build mathematical models to attempt to address this type of question. I will discuss some basic principles and methods that guide actuaries in their work and suggest some curriculum directions that can lead mathematically-inclined students to employment in this field.

The Banach-Tarski Paradox (pdf)
In 1924 Banach and Tarski proved the following result: any solid ball in the 3- dimensional space can be cut into a finite number of pieces and these pieces can be reassembled to yield two identical copies of the original ball. Also, one can cut a solid ball and reassemble the (finitely many) pieces to obtain any other solid ball! In this talk, I will convince you (hopefully) that these paradoxes are not as strange as they sound, and I will show you some ideas behind them.

Complete Order is Impossible (pdf)
Any large enough system must contain a structured subsystem. This is the idea of Ramsey theory, a branch of combinatorics. For example, among any six people, we can find either three people who mutually know each other or three people who mutually do not know each other. In this talk, I will give a brief introduction to Ramsey theory, as well as its manifestations in other branches of mathematics such as number theory, analysis and logic.

The Hairy Ball Theorem (pdf)
Imagine a soccer ball entirely covered in hair. The Hairy Ball Theorem says that you can’t comb the hair flat everywhere — there will always have to be a tuft of hair sticking up somewhere. This famous theorem of topology was first stated by Poincaré (late 1800s) and proved by Brouwer in 1912. A different way of saying this is that if you consider the Earth and look at the windspeed at each point, there is at least one place where the wind is not blowing. This will lead us into an exploration of some basic topological properties of surfaces and their relationship to dynamical systems.

“The Hardest Logic Puzzle Ever” and Logical Connectives (pdf)
In 1986 logician George Boolos published “The Hardest Logic Puzzle Ever”, a variation on the classic “Knights and Knaves” puzzle. Boolos’ puzzle is as follows: “Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for yes and no are da and ja, in some order. You do not know which word means which.” In order solve this puzzle the logical connectives encountered in mathematics are needed to construct questions. The properties of these connectives and the solution to many variants of this problem will be presented.

Inversion, or reflection about circles, is a transformation that generalizes the idea of reflection (mirror image) about a line. Inversion has several beautiful properties. For instance, lines and circles are transformed into lines and circles as well, and angles between curves are preserved under inversion. In this talk, we shall introduce this concept, discuss some of its most basic properties, and apply it to solve some problems in planar geometry.

Drunk Cops and Robbers: How To Catch A Thief… Slowly (pdf)
The game of Cops and Robbers can be played out, in a mathematical sense, on a graph—i.e., on a set of vertices and edges, like a square, star, hexagon, or other figure. In the game, the players designated as “cop” and “robber” take turns, respectively, moving from vertex to vertex along graph edges. Should the players ever occupy the same vertex at the same time, the robber is captured and the cop wins. The theory behind these graph pursuit-evasion games has been well studied. In 2011, a version of this game was investigated where the robber is moving randomly; a “drunk” robber. This talk will explore the reversed role: the cop is now “drunk” while the robber moves perfectly. The expected capture time will be demonstrated for the simplest 1-cop win graphs (paths), 2-cop win graphs (cycles) and, time permitting the k-d-regular tree.

If this talk were a movie, then the plot would be: How would the movie Taken (or Taken 2, the sequel) work out if Liam Neeson’s character had been drinking constantly?

Factorization Beyond the Integers (pdf)
We all know that any integer can be factored uniquely into primes. What if we look at other sets which have the same axiomatic properties as the integers? Does an analogous property hold? It turns out that the answer is ‘no,’ and we will explore how badly this can fail.

Durer’s Melencolia and Spherical Polyhedra (pdf)
Albrecht Durer (1471-1528) is regarded by some as the preeminent artist of the Renaissance in Northern Europe. Many different interpretations of the symbols included in his engraving the “Melencolia” have been given. There have been numerous interpretations of the shape of the stone block given on the left side of the figure. We investigate whether this block can be the model of a spherical polyhedron.
