seminar: "The higher topological complexity of subcomplexes of products of spheres"- Seminar of the session "Algebraic topology, geometric and combinatorial group theory" (2015)
speaker: Sergey Yuzvinsky (University of Oregon, Eugene)abstract: We consider polyhedral product space that is a subcomplex of product of spheres whose dimensions are of the same parity. For such a space we compute the s-topological complexity. In particular it gives the complexity of the complement to a complex general position arrangement of hyperplanes. It turns out that this complexity is determined by the simplicial complex from the structure of the product space (that is a skeleton of a simplex in case of an arrangement complement). The results have been obtained jointly with Jesus Gonzalez and Barbara Gutierrez.
