Weighted $L^p$-Liouville theorems for hypoelliptic partial differential operators on Lie groups [PDF]
, 2016 We prove weighted Lp-Liouville theorems for a class of second order hypoelliptic partial differential operators L on Lie groups whose underlying manifold is n-dimensional space. We show that a natural weight is the right-invariant measure Hˇ of .

Harnack inequality and no-arbitrage bounds for self-financing portfolios [PDF]
We give a direct proof of the Harnack inequality for a class of Kolmogorov operators associated with a linear SDE and we find the explicit expression of the optimal Harnack constant.

Hypoelliptic Laplacian and Orbital Integrals (AM-177) [PDF]
, 2011 This book uses the hypoelliptic Laplacian to evaluate semisimple orbital integrals in a formalism that unifies index theory and the trace formula. The hypoelliptic Laplacian is a family of operators that is supposed to interpolate between the ordinary ...

Semiclassical hypoelliptic estimates with a loss of many derivatives [PDF]
, 2014 International audienceWe study the pseudospectral properties of general pseudodifferential operators around a doubly characteristic point and provide necessary and sufficient conditions for semiclassical hypoelliptic a priori estimates with a loss of ...

Liouville theorems in halfspaces for parabolic hypoelliptic equations [PDF]
, 2006 We prove some one-side Liouville-type theorems in halfspaces for a class of evolution hypoelliptic equations. The operators we deal with are left translation invariant, and homogeneous of degree two, on homogeneous Lie groups on $mathbb{R}^{N+1}$
