A Carleson-type estimate in Lipschitz type domains for non-negative solutions to Kolmogorov operators [PDF]
, 2011 We prove a boundary Harnack inequalities for non-negative solutions to a class of second order degenerate differential operators of Kolmogorov type. Due to the degeneracy of the differential operator, we require geometric conditions on the boundary of ...

Harnack inequality and Liouville-type theorems for Ornstein-Uhlenbeck and Kolmogorov operators [PDF]
, 2020 We prove, with a purely analytic technique, a one-side Liouville theorem for a class of Ornstein-Uhlenbeck operators L0 in RN, as a consequence of a Liouville theorem at “t=−∞” for the corresponding Kolmogorov operators L0−∂t in RN+1.

Some Sharp Landau–Kolmogorov–Nagy-Type Inequalities in Sobolev Spaces of Multivariate Functions
Ukrainian Mathematical JournalFor a function $f$ from the Sobolev space $W^{1,p}(C)$ ($C\subset\mathbb{R}^d$ is an open convex cone), a sharp inequality that estimates $\| f\|_{L_{\infty}}$ via the $L_{p}$-norm of its gradient and a seminorm of the function is obtained. With the help of this inequality, a sharp inequality is proved, which estimates the ${L_{\infty}}$-norm of the ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 2, February 2025.Abstract One hypothesized mechanism that triggers deep‐focus earthquakes in oceanic subducting slabs below ∼300 km depth is transformational faulting due to the olivine‐to‐spinel phase transition. This study uses finite element modeling to investigate phase transformation‐induced stress redistribution and material weakening in olivine.

Undergraduate nursing students challenge misconceptions towards men in nursing: A mixed‐method study
Journal of Advanced Nursing, Volume 80, Issue 4, Page 1638-1651, April 2024.Abstract Aims To examine misconceptions towards men in nursing from the perspective of undergraduate nursing students. Specifically, this study sought to explore contributing factors of misconceptions and attributions of the success of men in nursing. Design A convergent parallel mixed‐method study.

A geometric statement of the Harnack inequality for a degenerate Kolmogorov equation with rough coefficients [PDF]
, 2019 We consider weak solutions of second-order partial differential equations of Kolmogorov-Fokker-Planck-type with measurable coefficients in the form ∂tu + (v,∇xu) = div(A(v,x,t)∇vu) + (b(v,x,t),∇vu) + f, (v,x,t) ε2n+1, where A is a symmetric uniformly ...
