Title:On the minimizers of Caffarelli-Kohn-Nirenberg inequality in
three dimension
Abstract: The minimizer of a functional inequality is often hard to find, and the minimizer of the famous Sobolev inequality are the least-energy solutions of the Yamabe equation in the Euclidean space, which can be viewed as the Euler-Lagrange equation for the Sobolev inequality. There is a far-reaching generalization of the Sobolev inequality by Caffarelli-Kohn-Nirenberg which includes also the Hardy inequality as a special case. The minimizer problem for CKN is solved except for the boundary-singular case in three dimension. We will show how to solve this problem in this talk. The existence of the minimizer is reduced to solving the Yamabe equation with a Hardy singularity.
