Title

:

"Face numbers of simplicial cell manifolds"
Abstract

:

A simplicial cell complex is roughly speaking a CW complex whose cells are all simplices. This notion is equivalent to that of simplicial poset in combinatorics. A simplicial complex is a simplicial cell complex, but two simplices in a simplicial cell complex may be glued together along more than one simplex on their boundaries. In this talk, I will discuss the characterization of face numbers of simplicial cell decompositions of some manifolds.
