Abstract

We study the concentration of measure in metric-measurable(mm)-spaces. We de ne the notion of concentration locus of a ag sequence of metric-measurable(mm)-spaces. Some examples of in nite group action on an in nite dimensional compact and non-compact manifold show the role played by the trajectory of concentration locus. We also provide some applications in Physics, which emphasize the role of concentration of measure in gravitational e ects.
