Description
I will present the recent work (joint with W. Chen, C. Jin, J. Lim,
and B. Ou) on systems of integral equations related to the
Hardy-Littlewood-Sobolev (HLS) inequality. The focus is on the
Euler-Lagrange equations of the HLS. These equations have been the
focal point in the field of analysis of nonlinear elliptical PDEs
including the Yamabe problem and the Nirenberg problem. We study the
symmetry, monotonicity, regularity and the asymptotic of the
solutions.
I will introduce some key futures of the main technique--the method
of moving planes for integral equations and will also present a
simple method for the study of regularity and obtain the optimal
integrability interval for solutions of a class of systems equations
as an application. The later is the key for us to obtain the exact
asymptotic of the solutions.
