"A compact non-formal closed G2 manifold with b1=1"
A G2 structure on a 7-dimensional Riemannian manifold (M,g) is determined by a stable of 3-form φ. It is said to be closed if dφ=0 and torsion-free if φ is parallel. The purpose of the talk is understanding certain topological properties of compact manifolds with a closed G2 structure that cannot be endowed with any torsion-free G2 structure. Namely, we outline the construction of such a manifold that is non-formal and has first Betti number b1=1.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
