  • Hypoelliptic Estimates and Spectral Theory for Fokker-Planck Operators and Witten Laplacians
    Bernard Helffer / Francis Nier
    There has recently been a renewal of interest in Fokker-Planck operators, motivated by problems in statistical physics, in kinetic equations, and differential geometry. Compared to more standard problems in the spectral theory of partial differential operators, those operators are not self-adjoint and only hypoelliptic. The aim of the analysis is to g...

  • Semi-Classical Analysis for the Schr Dinger Operator and Applications
    Bernard Helffer
    This introduction to semi-classical analysis is an extension of a course given by the author at the University of Nankai. It presents for some of the standard cases presented in quantum mechanics books a rigorous study of the tunneling effect, as an introduction to recent research work. The book may be read by a graduate student familiar with the clas...
