We apply Fourier transforms to homogeneous extensions of functions on S n−1 . This results in complex integral operators. The real and imaginary parts of these operators provide a pairing of stereological data that leads to new results concerning the determination of convex bodies as well as new settings for known results. Applying the Funk-Hecke theorem to these operators yields stability versions of the results.
Abstract. Suppose that we have the unit Euclidean ball in R n and construct new bodies using three operations -linear transformations, closure in the radial metric, and multiplicative summation defined byWe prove that in dimension 3 this procedure gives all origin-symmetric convex bodies, while this is no longer true in dimensions 4 and higher. We introduce the concept of embedding of a normed space in L 0 that naturally extends the corresponding properties of L p -spaces with p = 0, and show that the procedure described above gives exactly the unit balls of subspaces of L 0 in every dimension. We provide Fourier analytic and geometric characterizations of spaces embedding in L 0 , and prove several facts confirming the place of L 0 in the scale of L p -spaces.
For −1 < p < 1 we introduce the concept of a polar pcentroid body Γ * p K of a star body K. We consider the question of whether Γ * p K ⊂ Γ * p L implies vol(L) ≤ vol(K). Our results extend the studies by Lutwak in the case p = 1 and Grinberg, Zhang in the case p > 1.
The Busemann-Petty problem asks whether originsymmetric convex bodies in R n with smaller central hyperplane sections necessarily have smaller n-dimensional volume. It is known that the answer is affirmative if n ≤ 4 and negative if n ≥ 5. In this article we modify the assumptions of the original Busemann-Petty problem to guarantee the affirmative answer in all dimensions.
