Computer Science/Discrete Mathematics Seminar II

Why Extension-Based Proofs Fail
Faith Ellen
10:30am|Simonyi Hall 101 and Remote Access

A valency argument is an elegant and well-known technique for proving impossibility results in distributed computing. It is an example of an extension-based proof, which is modelled as an interaction between a prover and a protocol. Even though...

Special Year Seminar I

Tropical Subrepresentations and Matroids
Jaiung Jun
2:00pm|Simonyi 101

In their recent paper, Giansiracusa and Manaker introduced a notion of tropical subrepresentations of linear representations by considering linear actions on tropical linear spaces. In particular, this framework naturally brings matroids into the...

Towards the HZ- and Multiplicity Conjectures for Dynamically Convex Reeb Flows
Basak Gurel
9:15am|Remote Access

In this talk we discuss the multiplicity question for prime closed orbits of a dynamically convex Reeb flow on the boundary of a $2n$-dimensional star-shaped domain. Our first main result asserts that such a flow has at least n prime closed Reeb...
