### Oberseminar Differentialgeometrie: Sebastian Goette (Universität Freiburg), Vortrag: Extra Twisted Connected Sums and their $nu$-Invariants

##### Monday, 05.12.2022 16:15 im Raum SRZ 214

Abstract: In the first part of this talk, I will review compact manifolds with holonomy $G_2$, including some of their properties and some of the known constructions. In the second part, I will introduce Crowley's and Nordstr"om's $\nu$-invariants and sketch its computation for extra twisted connected sums.
