Abstract |
|
This paper is a study of Sum Theorems for various classes of topological spaces. Specifically, suppose that X is a topological space and {Fa} is a cover of X such that each Fα belongs to some class Q of topological spaces. When can we assert that X is in Q? We shall concentrate our attention on those cases where the elements of {Fα} are either all open or all closed and the collection {Fα} is a σ-locally finite cover of X. |
