SUMMARY:Special Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:LUCIA MARTIN MERCHAN\, UNIVERSITY OF WATERLOO\n\nAbout formalit
 y of compact manifolds with holonomy G2\n\nThe connection between holonomy
  and rational homotopy theory was\ndiscovered by Deligne\, Griffiths\, Mor
 gan\, and Sullivan\, who proved\nthat compact Kähler manifolds are formal
 . This led to the conjecture\nthat compact manifolds with special and exce
 ptional holonomy should\nalso be formal. In this talk\, I will discuss my 
 recent preprint\narXiv:2409.04362\, where I disprove the conjecture for ho
 lonomy G2\nmanifolds.\n\nMC 5479
