This is an announcement for the paper "A comment on the low-dimensional
Busemann-Petty problem" by Emanuel Milman.
Abstract: The generalized Busemann-Petty problem asks whether
centrally-symmetric convex bodies having larger volume of all
m-dimensional sections necessarily have larger volume. When m>3
this is known to be false, but the cases m=2,3 are still open. In
those cases, it is shown that when the smaller body's radial function
is a (n-m)-th root of the radial function of a convex body, the
answer to the generalized Busemann-Petty problem is positive (for
any larger star-body). Several immediate corollaries of this
observation are also discussed.
