Discrete module categories

A module over a topological ring is called 'discrete' if it is continuous when given the discrete topology. This concept is closely related to the duality between coalgebras and algebras and hence to the duality between the cooperations and operations of a (decent) cohomology theory. I will talk about discrete modules in general and the examples which come from topological K-theory.
