TETRAHEDRAL GEOMETRY/TOPOLOGY SEMINAR

         ANNOUNCEMENT

DATE:              Friday, April 3, 2009                     

LOCATION:    Hempfield High School, Room 213 (directions at http://www.millersville.edu/~tgts/)                

                           followed by dinner at a place to be determined.

4:30 TALK:  William Kronholm, Swarthmore College

                           “Homological Sensor Networks”

           Abstract: In this expository talk, we will discuss the recent applications of algebraic topology

                           to analysis of sensor networks. It is perhaps surprising that simple communication data from

                           sensor networks can answer questions about blanket coverage of the network over a domain

                           and pursuit/evasion problems. In each case, there is a homological criterion which is sufficient

                           to detect holes in the sensor network. We will see how to compute these homological criteria

                           from the Rips complex associated to the sensor network. I will also relate how I plan to use

                           these results in a math/art project with I am pursuing with my colleague Aaron Bocanegra (Art

                           Institute of California, L.A.).

     EVERYONE WELCOME
