Session 37. Wild algebraic and geometric topology |
One point unions preserve having the categorical universal covering |
| Ali Pakdaman, Golestan University, I. R. Iran |
|
In this talk I'll talk about categorical universal covering spaces of some wild
spaces, i.e. nonsemi-locally simply connected spaces. After classifying spaces
with the property of having the categorical universal covering by using the
Spanier groups, we show that one point unions preserve this property.
