Abstract
Classical integral geometry takes place in Euclidean space, but one can attempt to imitate it in any other metric space. In particular, one can attempt this in R<sup>n</sup> equipped with the metric derived from the p -norm. This has, in effect, been investigated intensively for 1<p<∞, but not for p=1. We show that integral geometry for the 1-norm bears a striking resemblance to integral geometry for the 2-norm, but is radically different from that for all other values of p . We prove a Hadwiger-type theorem for R<sup>n</sup> with the 1-norm, and analogues of the classical formulas of Steiner, Crofton and Kubota. We also prove principal and higher kinematic formulas. Each of these results is closely analogous to its Euclidean counterpart, yet the proofs are quite different.<p></p>
