MaPSS: Mathematical Postgraduate Seminar Series: Giulia Codenotti (Freie University, Berlin) -- Triangulated spheres and Pachner moves

Dear All, 

We are delighted to present the MaPSS Seminar topic of Monday 29/05; please see the
abstract below.  

**This Semester the Seminar will always run on Monday, at 5:00pm in 535A** 

Following the talk, there will be pizza on offer.  

Speaker: Giulia Codenotti (Freie University, Berlin) 

Title: Triangulated spheres and Pachner moves 

Abstract: In the world of discrete geometry-somewhere between combinatorics and
geometry- Pachner moves (or bistellar flips) are an important tool to "build up" complex
triangulations from more simple ones while preserving topological properties.  I will
give an introduction of basic objects in discrete geometry such as polytopes and
simplicial complexes and show with examples how Pachner moves can help both to devise
new questions and to answer others, spanning topics from combinatorics to topology.  

Supervisors, please encourage your students to attend.  

Thanks,
MaPSS Organisers
