            • Pedro Boavida: Configuration spaces on a triangulated manifold
Abstract: I will describe a model for configuration spaces (or, more generally, for the configuration category) of points on a manifold which is given in terms of a triangulation of the manifold. This gives rise to combinatorial descriptions for embedding calculus and associated spectral sequences, extending Sinha’s description when the manifold in question is the interval. Joint work with Pascal Lambrechts and Paul-Arnaud Songhafouou.
