摘要: In this paper, the author extends Ren's results in plane to the case of R2n,i.e., estimates the kinematic measure of a convex domain D1 with boundary ∑1 moving to another domain D0 with boundary ∑0 under the isometry group G in R2n. A sufficient condition for D0 contain D1 by using kinematic foundamatal formula and Poincare's formula in Rn is obtained.
