Abstract

We give a new proof of Aubin's improvement of the Sobolev inequality on Sn; under the vanishing of 1st-order moments of the area element and generalize it to higher-order moments case. By careful study of an extremal problem on Sn, we determine the constant explicitly in the 2nd-order moments case.
