TETRAHEDRAL GEOMETRY/TOPOLOGY SEMINAR

         ANNOUNCEMENT

DATE:              Friday, February 29, 2008                       

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:      Bogdan Doytchinov, Elizabethtown College

                           “Compactly Determined Spaces”

Abstract: A topological space Y is called compactly determined, if for every point y in Y and

every dense subset X of Y there exists a subset K of X whose closure in Y is compact and

contains y. I will address some naturally arising questions, like: are there any such spaces,

are there many, is the property of being compactly-determined inherited, preserved by

certain mappings, products, etc. The level of exposition should be accessible to advanced

undergraduates.
