Julie Bergner from
Notre Dame will introduce the idea of an nsimplex
and various ways to describe them, accompanied by lots of
pictures.
She will discuss how to put these simplices together to form a
simplicial complex, and from there go on to talk about polyhedra and
ways to build simplicial complexes from a graph. Come to Julie's
talk
and learn about these interesting and important mathematical ideas . .
. and find out whether a simplicial complex is complexly simple or
simply complex!
