SUMMARY:An AMS Talk with Dr. Thomas Riedel
CONTACT:Katherine Klotz\, 5028526787\, email:math@louisville.edu
DESCRIPTION:AMS at UofL is having UofL Math Professor, Dr. Thomas Riedel, g
 ive a talk overviewing functional equations. Hot drinks and snacks will be
  available. Anyone who is interested is welcome to join! The event will be
  on Monday, November 16, from 10 - 11 a.m. in NS LL30. The abstract for t
 he talk is below: \n\n"This talk aims to give an introduction to function
 al equations and also show how to ask new questions and create new problem
 s to solve. Functional equations have been used in mathematics since the m
 id 18th century arising around the same time as the definition of a functi
 on was introduced. The work on solving these equations gained momentum in 
 the 19th century most notably with the work of Cauchy. The focus will be o
 n functional equations of several variables such as Cauchy's Equation f(x+
 y)=f(x)+f(y), its generalization and several other equations arising from 
 questions characterizing certain functions or properties. We will also loo
 k at the question of stability of an equation: if a function g “almost
 ” satisfies a functional equation, does that mean there is a true soluti
 on that is “close” to g? This question was first asked by Ulam in 1940
  and answered by Hyers in 1941 and has since been studied extensively. "
