In this paper we will establish a
method of removing the Hausdorff assumption from certain convergence
space theorems. As specific applications the precise form of the closure of a
compact set in a regular non-Hausdorff space is given and the exact relationship
between cl and cl2 in a non-Hausdorff compact regular space is obtained.
Necessary and sufficient conditions that the transition space for this procedure be
topological or pretopological are found and a few embedding theorems are
obtained.
