Towards better bounds for link homology

Link homology, in particular Khovanov homology, comes in various guises, but in each case it leads to a well-defined computational problem. The most interesting cases are at least as hard as computing the Jones polynomial, which is already #P-hard. As of late I have been interested in the question whether the problem becomes polynomial-time computable when the treewidth of the input (appropiately defined) is bounded.

The talk will be a very general and light-weight introduction. I will give brief accounts of the history of homology, the ideas behind link homology, and reductions of chain complexes. Then I will present a result concerning connected sums.
