Abstract

We estimate the kinematic measure of one convex domain moving to another under the groupG of rigid motions in ℝ n . We first estimate the kinematic formula for the total scalar curvature ∫∂D0gD1Rdv of then−2 dimensional intersection submanifold ∂D0gD1. Then we use Chern and Yen's kinematic fundamental formula and our integral inequality to obtain a sufficient condition for one convex domain to contain another in ℝ n (≥4). Forn=4, we directly obtain another sufficient condition in ℝ4.
