[Binghamton Geometry/Topology Seminar] March 10 (CORRECTION: DATE AND ROOM)

[Lucas Sabalka]

This is a correction to the previous announcement.  The date was listed
incorrectly in the body of the email.  The talk is next Thursday, March 10.
The room has also been changed to accommodate more people, to Science II,
room 140.  The correct information is below.



                  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 mathematician, known for integrating topology with
its applications.  He is visiting us as part of our Dean's Speaker series of
lecturers.


*Date:*  Thursday, March 10, 2011
*Time:*  2:50-3:50pm
*Place:*  Science II room 140
 (followed by coffee/tea in the Anderson Reading Room, LN-2207).

*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.
