Finally, we take a look at the polyhedral cones underlying these objects and see how these geometric objects can give us insight into open problems about refined q-t Catalan numbers.<\/p>\n<p><strong>Bio:\u00a0<\/strong>Max Hlavacek is a Visiting Assistant Professor in the mathematics and statistics department at Pomona College.\u00a0 Previously, they were a graduate student at UC Berkeley and an undergraduate student at Harvey Mudd College.\u00a0 They are interested in problems in enumerative geometric combinatorics, particularly concerning discrete volumes of polytopes. \u00a0They love thinking about math with others, and especially enjoy learning about the interplay between polyhedral objects such as cones and polytopes and their friends\u2019 and collaborators\u2019 mathematical interests.<\/p>\n<p>The talk is based on joint work with Matthias Beck, Mitsuki Hanada, John Lentfer, Andr\u00e9s R.
