“Patterns in Permutations: the hidden and surprising structures that emerge from ordered lists”

with Lara Pudwell

Wednesday, June 2 at 4:00 pm and 7:00 pm ET (New York)

A “permutation” is a list where order matters.  Despite this humble definition, permutations offer a wealth of beautiful mathematics that can be applied across scientific disciplines.  Starting simply, with small ordered lists, mathematician Lara Pudwell demonstrates how smaller permutations can be embedded into larger permutations.  The results are both unexpected and delightful — not only do some familiar patterns suddenly appear, but this embedding gives rise to a host of interesting counting problems with connections not just to mathematics, but to computer science, chemistry, and more.

Special introduction by Dr. Jennifer Quinn, Professor of Mathematics, University of Washington Tacoma, and President, Mathematical Association of America.

This is a live-streamed event.  Occasional video recordings are made available for a fee at videos.momath.org.
