For any two graphs G and H, Lovász defined a cell complex Hom with an idea that topological and algebraic invariants of these complexes should provide non-trivial lower bounds for chromatic numbers of graphs.
In this talk, I will present some recent results about topological properties of certain classes of Hom complexes.
