Stable solutions of symmetric systems involving hypoelliptic operators [PDF]

open access: yesJournal of Functional Analysis, 2017
Let X and Y be two noncommuting vector fields in an open set Ω in a manifold M equipped with a sub-Riemannian structure. We examine stable solutions of the following symmetric system ∆XY ui = Hi(u1, · · · , um) in Ω for 1 ≤ i ≤ m, when the operator ∆XY ...

Tug-of-war with Kolmogorov [PDF]

open access: yesJournal of Differential Equations, 2022
We introduce a new class of strongly degenerate nonlinear parabolic PDEs ((p − 2)∆ ∞,X + ∆X )u(X,Y, t) + (m + p)(X · ∇Y u(X,Y, t) − ∂tu(X,Y, t)) = 0, (X,Y, t) ∈ R × R × R, p ∈ (1,∞), combining the classical PDE of Kolmogorov and the normalized p-Laplace ...

On the fine properties of parabolic measures associated to strongly degenerate parabolic operators of Kolmogorov type [PDF]

open access: yesAdvances in Mathematics, 2020
We consider strongly degenerate parabolic operators of the form L := ∇X · (A(X,Y, t)∇X) +X · ∇Y − ∂t in unbounded domains Ω = {(X,Y, t) = (x, xm, y, ym, t) ∈ R m−1 × R× R × R× R | xm > ψ(x, y, t)}.

Liouville theorems for Kirchhoff-type parabolic equations and system on the Heisenberg group

open access: yesOpen Mathematics, 2023
In this article, the Liouville theorems for the Kirchhoff-type parabolic equations on the Heisenberg group were established. The main technique for proving the result relies on the method of test functions.

One-dimensional inverse problems of determining the kernel of the integro-differential heat equation in a bounded domain

open access: yesNonautonomous Dynamical Systems, 2023
The integro-differential equation of heat conduction with the time-convolution integral on the right side is considered. The direct problem is the initial-boundary problem for this integro-differential equation.
