چکیده
Abstract. The aim of this paper is to study properties of sections of convex bodies with respect to different types of measures. We present a formula connecting the Minkowski functional of a convex symmetric body K with the measure of its sections. We apply this formula to study properties of general measures most of which were known before only in the case of the standard Lebesgue measure. We solve an analog of the Busemann-Petty problem for the case of general measures. In addition, we show that there are measures, for which the answer to the generalized Busemann-Petty problem is affirmative in all dimensions. Finally, we apply the latter fact to prove a number of different inequalities concerning the volume of sections of convex symmetric bodies in R and solve a version of generalized Busemann-Petty problem for sections by k-dimensional subspaces.

The Generalized Busemann-petty Problem with Weights
This question is known as the generalized Busemann-Petty problem. For i = n − 1, the problem was posed by Busemann and Petty [2] in 1956. It has a long history, and the answer is affirmative if and only if n ≤ 4; see [3], [8], [11]. For the generalized Busemann-Petty problem the following statements are known. If i = 2, n = 4, an affirmative answer follows from that in the case i = n − 1. If 3 ...
متن کاملOn a Generalization of the Busemann–Petty Problem
The generalized Busemann–Petty problem asks: If K and L are origin-symmetric convex bodies in Rn, and the volume of K ∩H is smaller than the volume of L ∩H for every i-dimensional subspace H, 1 < i < n, does it follow that the volume of K is smaller than the volume of L? The hyperplane case i = n−1 is known as the Busemann–Petty problem. It has a negative answer when n > 4, and has a positive a...
متن کاملThe Lower Dimensional Busemann-petty Problem for Bodies with the Generalized Axial Symmetry
The lower dimensional Busemann-Petty problem asks, whether n-dimensional origin-symmetric convex bodies, having smaller i-dimensional sections, necessarily have smaller volumes. For i = 1, the affirmative answer is obvious. For i > 3, the answer is negative. For i = 2 and i = 3, the problem is still open, except when the body with smaller sections is a body of revolution. In this case the answe...
متن کاملMay 21, 2014 AN ISOMORPHIC VERSION OF THE BUSEMANN-PETTY PROBLEM FOR ARBITRARY MEASURES
The Busemann-Petty problem for an arbitrary measure μ with non-negative even continuous density in R asks whether origin-symmetric convex bodies in R with smaller (n − 1)-dimensional measure μ of all central hyperplane sections necessarily have smaller measure μ. It was shown in [Zv] that the answer to this problem is affirmative for n ≤ 4 and negative for n ≥ 5. In this paper we prove an isomo...
متن کاملAn Analytic Solution to the Busemann-Petty Problem on Sections of Convex Bodies
We derive a formula connecting the derivatives of parallel section functions of an origin-symmetric star body in Rn with the Fourier transform of powers of the radial function of the body. A parallel section function (or (n − 1)dimensional X-ray) gives the ((n − 1)-dimensional) volumes of all hyperplane sections of the body orthogonal to a given direction. This formula provides a new characteri...
