Speaker: Logan Opperman
Title: Continuous Inspection Schemes
Abstract: We compare simple sampling methods with sequential sampling methods in continuous inspection schemes. 

Monday, October 2
Speaker: Katherine Shoemaker
Title: Digital Topology
Abstract: This talk will present how computers understand topological properties and why topology is needed for image analysis algorithms.

Monday, September 25
Speaker: Samuel Hokamp
Title: Weak*-closed Rotation Invariant Subspaces of L2(S)
Abstract: In which the question of what weak*-closed rotation invariant subspaces of L2(S) look like is answered.

Monday, September 18
Speaker: Sam Carolus
Title: The Protean Chromatic Polynomial
Abstract: I present some interesting facts about the chromatic polynomial of a graph.  This was adapted from a talk at the Fall Sectional meeting of the AMS given by Dr. Bruce Sagan.

Monday, September 11
Speaker: Serge Phanzu
Title: Two Problems in Hypercyclicity
Abstract: We give some basic definitions for hypercyclicity and prove two interesting results.

Monday, August 28
Speaker: Samuel Hokamp
Title: An Introduction to Nets and Their Use in Topology
Abstract: In this talk, we will consider an example in which sequences are insufficient in fully characterizing the topology on a set. We will then present the definition of a net and detail how this generalization of sequences is precisely the notion we are seeking in order to characterize the topology on a set. 


Spring 2017 Semester


Friday, April 28
Speaker: John Haman
Title: Bayesian Modeling in Political Science
Abstract: Rich Americans tend to vote Republican, but rich states swing Democrat. Conversely, poor Americans tend to vote Democrat, but poor states are often won by Republicans. I will talk about using statistical inference to examine the effect of income on political opinion, and how to reconcile these patterns.

Friday, April 14
Speaker: Tom Tuberson
Title: Is Random Actually Random? 
Abstract: If given a random list of numbers, is it always possible to find a pattern in it? Is there some algorithm to tell what the next few numbers in the list are? In this talk we explore possible patterns behind such lists as I present the thought process I went through in the recent past as I pondered the matter. 

Friday, April 7
Speaker: Sam Hokamp
Title: Minesweeper and a Millenium Problem
Abstract: In this talk, we consider the complexity of the game Minesweeper and show where it fits into the larger world of other NP-complete problems, such as the Traveling Salesman Problem and the Boolean Satisfiability Problem. We will then discuss the P versus NP Millennium Problem and show how a solution to Minesweeper will solve it.

Friday, March 31
Speaker: Sam Carolus
Title: Category Theory: A Primer
Abstract: Category theory is a way to study interactions between different mathematical structures. We will give some definitions and some uses, then discuss examples, including some we all know and love. 

Friday, March 24
Speaker: Nick Papalia
Title: Zero, A Brief History
Abstract: I will be talking about how zero was not a number at all to begin with and some interesting problems that came about from not having zero as a number. 

Friday, March 17
Speaker: Andrea Alt
Title: Supporting Math Emporium Students' Learning through Short Instructional Opportunities
Abstract: This talk summarizes a study conducted in the BGSU math emporium. The study focuses on the concept of including traditional math classroom experiences in a math emporium course. The aim of this study is to gain an insight into the opinions of students about which emporium structure they prefer as well as which they believe they can be more successful in. Also, this study will analyze emporium students' academic success in both scenarios. To accomplish these goals, two sections of Algebra II in the math emporium were offered the option to attend short instructional opportunities led by the instructor.

Friday, March 3
Speaker: James Munyon
Title: A Statistical Analysis of Motor Vehicle Fatalities in the United States
Abstract: 35092 people died in motor vehicle crashes in 2015, a 7.2% increase from 2014 after several years of decrease. The purpose of my thesis is to investigate which factors correlated with high fatality risk for the 2015 set of crashes. Primary methods of analysis are logistic regression models and decision tree models. We will find expected risk factors such as alcohol use, drug use, and lack of seat belt use, but a few surprises may be in store.

Friday, February 24
Speaker: Serge Phanzu
Title: The Poincaré Inequality
Abstract: The Poincaré Inequality is a result in the theory of Sobolev spaces, named after the French mathematician Henry Poincaré. The inequality allows one to obtain bounds on a function using bounds on its derivatives and the geometry of its domain of definition.

Friday, February 17
Speaker: Luke Dechow
Title: A Brief Introduction to Some Historically Important Groups
Abstract: For a few select groups, we'll discuss the questions, problems, or conjectures that brought rise to them, their constructions and/or presentations, and some important properties they have or applications they're used in (along with whatever else I feel like). Slight tangents may be made into coding theory, Moufang loops, or current problems in group theory.

Friday, February 10
Speaker: Garrett Ebbers
Title: Think You Know Numbers? Think Again
Abstract: This talk will summarize the book Number Freak by Derrick Niederman. We will discuss interesting facts about almost every number from 1 to 200. A majority of these facts should be unknown to the audience and will come from math, history, pop culture and more.

Friday, February 3
Speaker: Jake Laubacher
Title: Every Cow Has a Cowlick
Abstract: The Hairy Ball Theorem has some interesting applications. We'll present some of them here.

Friday, January 27
Speaker: Mark Medwid
Title: Gromov Hyperbolicity
Abstract: In this talk we'll discuss what it means for a space to be hyperbolic (in the sense of Gromov), or spaces that have triangles that are "thin" in some precise sense. We will discuss some basic geometric properties of these spaces, as this notion of hyperbolicity is used frequently in geometric group theory.  

Friday, January 20
Speaker: David Walmsley
Title: Advice on Applying for Academic Jobs
Abstract: A good number of BGSU graduate students will end up applying for jobs in academia. I'll discuss the job application process, how to present a strong case for yourself, and discuss what interviewing is like. I'll also provide some helpful articles that delve deeper into these topics.
