About formality of compact manifolds with holonomy G2
The connection between holonomy and rational homotopy theory was discovered by Deligne, Griffiths, Morgan, and Sullivan, who proved that compact Kähler manifolds are formal. This led to the conjecture that compact manifolds with special and exceptional holonomy should also be formal. In this talk, I will discuss my recent preprint arXiv:2409.04362, where I disprove the conjecture for holonomy G2 manifolds.
