Abstract:

I will finally get to some of the hard work and show, if time permits, the following two results:

1. Assuming that *V* is the subobject and product closure of a very nice category *S* of topological objects and that *S* contains a very nice injective *K*, then *K* is also injective in *V*.

2. The inclusion of the weak objects in *V* has a left adjoint and the inclusion of the strong objects has a right adjoint.
