| Wednesday, March 15 Transformation Groups Seminar Time: 10:30 Room: MC 107 Speaker: Matthias Franz (Western) Title: Formality of Davis-Januszkiewicz spaces I will present a proof that the Davis-Januszkiewicz space DJ(K) is integrally formal, meaning that its integral cochain algebra is quasi-isomorphic to its cohomology (which is the Stanley-Reisner ring of K). If time permits, I will sketch a proof that toric manifolds (or, more generally, equivariantly formal toric varieties) are formal in the sense of rational homotopy theory. |
