A Grushin problem for Bismut's hypoelliptic Laplacian
Xingfeng Sang, Francis White, Francis Nier
We study in this article the combined asymptotic analysis of Bismut's hypoelliptic Laplacian, in the high friction b 0+ and possibly low temperature h 0…

Global subelliptic estimates for geometric Kramers-Fokker-Planck operators on closed manifolds
Francis Nier, Xingfeng Sang, Francis White
In this article we reconsider the proof of subelliptic estimates for Geometric Kramers-Fokker-Planck operators, a class which includes Bismut's hypoelliptic Laplacian, when the bas…
