Title:
New invariants in G_2 topology
Speaker:
Abstract:
The \nu-invariant is a Z/48-valued invariant of G_2-structures on 7-manifolds M up to homotopies and diffeomorphisms. In this talk I will report on joint work with Johannes Nordström about computations of the \nu-invariant for twisted connected sum G_2-manifolds.
