# Mathematics and Statistics Colloquium (Dec 1)

Speaker: Dr. Pamela E. Harris (University of Wisconsin at Milwaukee)

Time and location: Thursday, December 1st, 4:00-5:00pm, IES 110 (Tea/coffee beforehand at 3:30pm in IES 116)

Title: Multiplex juggling sequences and Kostant's partition function

Abstract: Multiplex juggling sequences are generalizations of juggling sequences (describing throws of balls at discrete heights) that specify an initial and terminal configuration of balls and allow for multiple balls at any particular discrete height. Kostant¿s partition function is a vector function that counts the number of ways one can express a vector as a nonnegative integer linear combination of a fixed set of vectors. What do these two families of combinatorial objects have in common? Attend this talk to find out!

About the speaker: Dr. Harris is an Associate Professor in the Department of Mathematical Sciences at the University of Wisconsin at Milwaukee. She also cohosts the podcast Mathematically Uncensored and is the President and co-founder of Lathisms: Latinxs and Hispanics in the Mathematical Sciences. Her research interests are in algebra and combinatorics, particularly as these subjects relate to the representation theory of Lie algebras.
