摘要
We prove two principal kinematic formulas for germs of closed definable sets in R-n, that generalize the Cauchy-Crofton formula for the density due to Comte and the infinitesimal linear kinematic formula due to the author. In this setting, we do not integrate on the space of euclidean motions SO(n) x R-n, but on the manifold SO(n) x Sn-1. (c) 2022 Elsevier Inc. All rights reserved.
