[Binghamton Geometry/Topology Seminar] March 10

[Lucas Sabalka]

                  BINGHAMTON GEOMETRY/TOPOLOGY SEMINAR

Our next seminar talk is by Dr. Robert Ghrist, the Andrea Mitchell Penn
Integrates Knowledge Professor of Mathematics and Electrical Systems and
Engineering at the University of Pennsylvania.   Dr. Ghrist is a
world-renowned applied mathemetician, known for integrating topology with
its applications.  He is visiting us as part of our Dean's Speaker series of
lecturers.


*Date:*  Thursday, March 3, 2011
*Time:*  2:50-3:50pm
*Place:*  Library North 2205 followed by coffee/tea in the Anderson Reading
Room.

*Speaker:*  Robert Ghrist (U Penn)
Title:  Euler Calculus for Data

*Abstract:* This talk explains an ingenious integral calculus based on Euler
characteristic, stemming from work on sheaves due to MacPherson and
Kashiwara in the 1970s, and connecting back further to classical integral
geometry. I will emphasize (1) its novel utility in data management,
particularly in aggregation of redundant data and inverse problems over
sensor networks; and (2) how issues of numerical computation, inspired by
applications, leads to fascinating new connections with Morse theory.
