I've Gotta Get a Message to You: An Introduction to Error-Correcting Codes

Speaker: Neville Fogarty
Christopher Newport University

Abstract: Suppose you want to send a message to a friend, but you know that your message might get corrupted along the way. How can you make it so that your friend can tell that something went wrong? Is it possible that your friend could even figure out what went wrong with high probability? Importantly, can you do this without spending too much time or money?

 
Welcome to the world of error-correcting codes. We will explore the primary goals of error detection and correction in transmitted messages through examples and applications from the real world. We will also look at different types of codes, including one well-studied class of codes—cyclic codes—which we'll use to discuss how we can adapt codes to suit particular purposes. No prior knowledge of coding theory is assumed!

Bio: Neville Fogarty is an assistant professor of mathematics at Christopher Newport University. He earned a B.S. in mathematics and economics from Washington and Lee University in 2010, and a Ph.D. in mathematics from the University of Kentucky in 2016. His area of specialty is algebraic coding theory, and in his free time he constructs crossword puzzles.

 

We meet for a social with the speaker from 3:30 to 4:00. Presentations are from 4:00-5:00 p.m. in Ruffner 356. Please join us!
