    Convex Measures and Associated Geometric and Functional Inequalities
    (2015-07) Melbourne, James
    Convex measures represent a class of measures that satisfy a variant of the classical Brunn-Minkowski Inequality. Background on the associated functional and geometric inequalities is given, and the elementary theory of such measures is explored. A generalization of the Lovasz and Simonovits localization technique is developed, and some applications to large deviations are explained. In a more geometric direction, a modified Brunn-Minkowski Inequality is explored on some discrete spaces. The significance of such a notion is in its potential to serve as a definition for a lower Ricci curvature bound in non-smooth spaces.
