Convex Geometry

Definition

Curvature measures are mathematical tools that quantify the curvature of a set in a Euclidean space, providing insights into its geometric properties. They play a crucial role in the study of convex bodies and help describe how a shape bends or curves in various dimensions. Understanding curvature measures is essential for exploring recent developments and open problems in convex geometry, as they relate to how these geometric entities can be analyzed and categorized based on their curvature characteristics.
