Spaces of Analytic Functions and Optimal Polynomial Approximants 

Chris Felder
Butler Alumus '16
Mathematics & Statistics PhD
Graduate Student
Washington University in St. Louis

Friday, March 22, 2019
2:30 PM Meet & Greet
3:00 PM Talk
Jordan Hall 236 

In this talk, we will begin by defining the Hardy space of analytic functions on the unit disk and then generalize this definition to include Dirichlet-type spaces. We will explore some properties of these spaces and discuss, in some sense, how to use polynomials to approximate reciprocals of functions in the space. This talk will be accessible to undergraduate students who have completed the calculus sequence and understand basic complex analysis.


Join us at 2:30 for an informal meet and greet with Chris and hear about his math research experiences here at Butler and then on into graduate school.  Then stay for his talk at 3:00 PM!  Snacks will be provided.


Ben Linowitz, Ph. D., Assitant Professor of Mathematics, Oberlin College
The ABC Conjecture

Friday, February 8, 2019
3:00 p.m.
Jordan Hall 216

The ABC conjecture is a central open problem in number theory.  If true, it would imply a number of incredible resultls, some of which have earned Fields medals in the past.  Given these amazing consequences, it is perhaps surprising that the conjecture is remarkably easy to state; it concerns the integer solutions to the equation A+B=C.  In 2012 Sinchi Mochizuki announced a 500-page proof of the conjecture, and it is only now that mathematicians are coming to terms with his proof and whether or not it is valid.  In this talk Dr. Linowitz will state the conjecture, indicate some of its consequences and prove an analogue for polynomials.

Please joint us; all events are open to the public.

2018 Fall Colloquia

Ryann Cartor

Graduate Student - Department of Mathematics
University of Louisville

An Introduction to Multivariate Cryptography

This talk will provide an introduction to post-quantum cryptography, specifically multivariate cryptography.  we will discuss the original multivariate cryptosystem, C*, first proposed and studied by Matsumoto and Imai and published in Springer's Lecture Notes in Computer Science Series, EUROCRYPT '88.  The scheme has since been broken, and modifications of the scheme have been added in the hopes to regain security.  We will review those modifications and discuss areas of interest in the field today.

Dr. Geoffre Sherman, Lecturer, IUPUI

Data and Statistics in sports


Dr. Sherman brings more than a decade of industry experience to the Sport Management students in the School of Health and Human Sciences (SHHS).  His experiences range from the operations of a college athletic department to professional teams.  He currently works with the Indianapolis Colts, Indianapolis Indians, Indiana Pacers, and Indiana Fever to bring the industry into the classroom.  Also attending the talk will be a guest of Dr. Sherman, Spencer Anderson, who works with the Indiana Pacers.


Ken Jacobs, Ph. D. - Northwestern University
Boas Visiting Assistant Professor 

Heights and dynamical systems

What can arithmetic tell us about geometry and dynamics?  It turns out, quite a bit!  Height functions form an important bridge between these subjects, allowing different notions of arithmetic complexity to be translated into geometric phenomena.  In this talk, we'll discuss the role of height functions in studying dynamical systems coming from the iteration of polynomial and rational functions.

Please join us afterward for Jimmy Johns and a Q&A time with Dr. Jacobs.
