In the talk we discuss singularity formation of Einstein metrics
as the underlying spaces degenerate or collapse. The usual analytic tools
such as uniform Sobolev inequalities and nonlinear a priori estimates are
unavailable in this context. We will describe an entirely new way to
handle these difficulties, and construct degenerating Ricci-flat metrics
with quantitative singularity behaviors.
