TETRAHEDRAL GEOMETRY/TOPOLOGY SEMINAR

         ANNOUNCEMENT

DATE:              Friday, November 2, 2007            

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:      Elizabeth Sell, Millersville University

                           “Geometric and topological invariants of singularities”

                                    Abstract: The study of singularities is at the crossroads of several areas of mathematics,

                           including topology, algebraic geometry, and analytic geometry.  In this talk, I will give

                           a general introduction to the study of isolated singularities in algebraic geometry.  In

                           particular, I will describe some of the geometric and topological invariants associated

                           to plane curve singularities and normal surface singularities, and will conclude with a

                           description of my work on surface singularities defined by an equation of the form

                           z^n=f(x,y).  No prior knowledge of algebraic geometry is necessary.

     EVERYONE WELCOME

       PLEASE FORWARD THIS ANNOUNCEMENT TO ANYONE INTERESTED
