Abstract: 

I will begin by discussing a number of equivalent approaches to defining the end set of a manifold. There is an end corresponding to
each component of the complement of compact sets for sufficiently large compact sets. I will then define the genus of an end
in the three manifold setting and will describe how to construct simply connected three manifolds with a countable dense set of
ends of specified generii. The construction will of course involve Cantor sets.
