Abstract : In this talk I will define the Gromov-Hausdorff distance defined on the space of all compact metric spaces and give numerous examples. This concept is very useful in itself but, more importantly, is an excellent example of “intrisification” of an extrinsic notion (that is depends on the embedding. For example, whether a subset is closed or not is an extrinsic notion but, compactness is an intrinsic notion.). This distance is obtained from an intrinsic notion of distance between compact subsets of a metric space, the Hausdorff distance. There are no prerequisites.
