报告摘要:In this talk, I will present some results about the existence and concentration phenomenon of solutions for some fractional Yamabe type problems. One is the existence of clustered solutions to low-order perturbations of fractional Yamabe equations, which are slightly supercritical, under certain geometric and dimensional assumptions, these solutions certainly exhibit non-isolated blow-up. The other is the instability of the fractional Yamabe problem under perturbations on the linear term, defined on the conformal infinity of an asymptotically hyperbolic manifold.

报告摘要:I will introduce some recent results on the existence of sign changing solutions for a fractional critical problem and a Paneitz type critical problem. Based on the reduction method, we construct a solution with the shape of a tower of sign changing bubbles for these problems.
