About the event

Speaker: Grigory Solomadin 

Topic: Billera-Lee construction for polytopes. 

Abstract: We will discuss the construction of any simplicial complex with g-vector being an M-vector as a collection of visible facets of a cyclic polytope in R^{d+1}. This will complete the proof of sufficiency of g-theorem by Billera and Lee.
