Compactness Criteria for the Resolvent of the Fokker-Planck operator
arXiv:1510.01567
Abstract
In this paper we study the spectral property of a Fokker-Planck operator with potential. By virtue of a multiplier method inspired by Nicolas Lerner, we obtain new compactness criteria for its resolvent, involving the control of the positive eigenvalues of the Hessian matrix of the potential.
