Uniqueness of positive solutions with critical exponent and inverse square potential

Abstract

We obtain the local uniqueness of positive solution for equation with inverse square terms in a smooth bounded domain. This is done by analyzing the Green function and the blow up profile of positive solution of some critical exponent problems with Hardy potential in a smooth bounded domain. We also determine the critical constant of the blow up behavior. This extends the result of Grossi [13] and Cerqueti [5] and Cao-Peng [3] to singular operators.
