On Classes of Spaces (Weakly) Built out of A

Abstract: Given a fixed space A, one can consider the collection of spaces built out of A using the same operations one uses to build CW complexes out of spheres. In this talk, we will discuss the theory of these so-called A-cellular spaces, paying most attention to classes of spaces which have an extra closure property. There is a beautiful characterization of spaces A for which the A-cellular spaces have this extra closure property. Furthermore, there is an obstruction related to this extra closure property which we will discuss.

We meet weekly on Thursday afternoons, with the third meeting of each month in Altoona. If you are interested in giving a talk in our seminar please contact one of the coordinators for the Spring 2006 semester: Aissa Wade and Wojciech Dorabiala.
