Homotopy n-types are topological spaces with trivial homotopy groups in
dimension greater than n. They arise naturally in algebraic topology
and category theory. Both these areas of mathematics have seen the
development of models of n-types. In this talk I will describe some of
these models and I will address the question on how to compare some of
them. I will also talk about some recent results I have obtained about
this comparison problem.
