This is an announcement for the paper "On Gaussian marginals of
uniformly convex bodies" by Emanuel Milman.
Abstract: We show that many uniformly convex bodies have Gaussian
marginals in most directions in a strong sense, which takes into
account the tails of the distributions. These include uniformly
convex bodies with power type 2, and power type p>2 with some
additional type condition. In particular, all unit-balls of subspaces
of L_p for 1<p<\infty have Gaussian marginals in this strong sense.
Using the weaker Kolmogorov metric, we can extend our results to
arbitrary uniformly convex bodies with power type p, for 2<=p<4.
These results are obtained by putting the bodies in (surprisingly)
non-isotropic positions and by a new concentration of volume
observation for uniformly convex bodies.
