# Combinatorics: Bruno Benedetti (U. Miami) "Local constructions of manifolds"

11:00am to 1:00pm

## Location:

CS building, room B500, Safra campus, Givat Ram

Speaker: Bruno Benedetti, U. Miami

Title: Local constructions of manifolds

Abstract: Starting with a tree of tetrahedra, say you are allowed to

recursively glue together some two boundary triangles that have nonempty

intersection. You may perform this type of move as many times you want.

Let us call "Mogami manifolds" the triangulated 3-manifolds (with or

without boundary) that can be obtained this way. Mogami, a quantum

physicist, conjectured in 1995 that all triangulated 3-balls are Mogami.
