Generalizations of the Busemann-Petty problem for sections of convex bodies

Boris Rubin, Gaoyong Zhang

Research output: Contribution to journalArticlepeer-review


We present generalizations of the Busemann-Petty problem for dual volumes of intermediate central sections of symmetric convex bodies. It is proved that the answer is negative when the dimension of the sections is greater than or equal to 4. For two- three-dimensional sections, both negative and positive answers are given depending on the orders of dual volumes involved, and certain cases remain open. For bodies of revolution, a complete solution is obtained in all dimensions.
