Alexandrov Spaces with Integral Current Structure

Differential Geometry 2017-03-27 v1

Abstract

We endow each closed, orientable Alexandrov space (X,d)(X, d) with an integral current TT of weight equal to 1, T=0and{(}T)=X\partial T = 0 and \set(T) = X, in other words, we prove that (X,d,T)(X, d, T) is an integral current space with no boundary. Combining this result with a result of Li and Perales, we show that non-collapsing sequences of these spaces with uniform lower curvature and diameter bounds admit subsequences whose Gromov-Hausdorff and intrinsic flat limits agree.
