One of the most robust pieces of evidence for dark matter comes from the formation and evolution of the intricate large-scale structure of the Universe. 
By comparing the results of N-body (and hydro) simulations with observations, one can infer some important properties that the dark matter particles should have (mass, maximal scattering cross section etc). However there comes a point where we lack sufficient resolution to distinguish between different models. In this talk, I will show that analysing the topology of the large-scale-structure in the Universe could provide a wealth of information that has been so far inaccessible and may help discriminate between dark matter models.
