Wilderich Tuschmann (Karlsruhe): Collapsing and curvature operator

Academic or specialist Colloquium / Congress / Forum

Extending work of Cheeger and Gromov, Lott has recently initiated a theory of collapsing under a lower bound on the curvature operator in which manifolds with almost nonnegative curvature operator play a fundamental role. I will discuss constructions of manifolds with an obstruction to this latter property in the framework of his work.
