Hello everyone,

Today we are very happy to have Birch speaking in seminar. His title and abstract are below.

Also, we have two more talks this semester. Michelle Chu from UCSB next week and Hailey Bodiford in three weeks. 

Title: Prime Decomposition of Surfaces by Crushing 

Speaker: Birch Bryant, Oklahoma State University 

Date: Apr 16, 2019 

Time: 3:30 PM 

Room: MSCS 5109 

Abstract: Joint project with William Jaco. Following the steps for the prime decomposition of 3-manifolds laid out in the Jaco & Rubinstein paper “0- Efficient Triangulations of 3- Manifolds” we construct the analogous (and well known) result for surfaces. That being the torus and real projective plane are the prime surfaces with respect to the connect sum operation on surfaces. Further the decomposition of surfaces into prime elements can be written uniquely up to homeomorphism.
