Multiscale problems and homogenization for second-order Hamilton-Jacobi equations
, 2007 We prove a general convergence result for singular perturbations with an arbitrary number of scales of fully nonlinear degenerate parabolic PDEs. As a special case we cover the iterated homogenization for such equations with oscillating initial data ...

Gaussian estimates for hypoelliptic operators via optimal control
, 2007 We obtain Gaussian lower bounds for the fundamental solution of a class of hypoelliptic equations, by using repeatedly an invariant Harnack inequality.

Harnack Inequality for Hypoelliptic Second Order Partial Differential Operators [PDF]
, 2016 We consider non-negative solutions (Formula presented.) of second order hypoelliptic equations(Formula presented.) where Ω is a bounded open subset of (Formula presented.) and x denotes the point of Ω.

Smoothness of solutions of differential equations of constant strength in Roumieu spaces [PDF]
, 2023 We show in this work that every solution of hypoelliptic differential equations with constant strength with coefficients in Roumieu spaces is in some Roumieu ...

A parametrix for step-two hypoelliptic diffusion equations
, 1986 In this paper I construct a parametrix for the hypoelliptic diffusion equations ( ∂ / ∂ t − L ) u = 0 (\partial /\partial t - L)u = 0 , where
