On the surface area measure of convex bodies
WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 … WebThe surface area measure induced by S is the Borel measure nS defined in Sd 1 satisfying nS(A) := jfr 2S : nr 2Agj for any Borel subset AˆSd 1. In the case when S coincides with ¶C, we obtain the well-known measure n¶C called the surface area measure of the convex body C. For this measure, the following well-known relation takes place: Z Sd ...

Naturally, the Lp surface area measure h 1−p K SK for a convex body K∈ K n (o) (see Section 2 for notations) can be defined from (2.4), and consequently the Lp Minkowski problem WebWe will show that the characterization of these mean section bodies is equivalent to the solution of the general Minkowski problem, namely that of giving the characteristic properties of those measures on the unit sphere which arise as surface area measures (of arbitrary degree) of convex bodies.

A related extremal problem shows that half spaces minimize surface area for a Gaussian distribution in Rn [3]. One variation on these results is to consider log-concave measures µ supported on a convex body K, i.e. a closed and boundedconvex set. Recall that theMinkowski measure µ+(S) …
