Interior regularity of obstacle problems for nonlinear subelliptic systems with VMO coefficients [PDF]

open access: yesJournal of Inequalities and Applications, 2018
This article is concerned with an obstacle problem for nonlinear subelliptic systems of second order with VMO coefficients. It is shown, based on a modification of A-harmonic approximation argument, that the gradient of weak solution to the corresponding

Regularity for sub-elliptic systems with VMO-coefficients in the Heisenberg group: the sub-quadratic structure case

open access: yesAdvances in Nonlinear Analysis, 2020
We consider nonlinear sub-elliptic systems with VMO-coefficients for the case 1 < p < 2 under controllable growth conditions, as well as natural growth conditions, respectively, in the Heisenberg group.

Medial closing wedge distal femoral varus osteotomy alters the stress distribution pattern of the patellofemoral joint: An evaluation using computed tomography osteoabsorptiometry. [PDF]

open access: yesJ Exp Orthop
Abstract Purpose This study aimed to (1) assess changes in subchondral bone density distribution across patellofemoral (PF) joint before and after medial closing wedge‐distal femoral varus osteotomy (MCW‐DFVO) and (2) determine correlation between PF alignment and changes in bone density distribution.

Partial Hölder continuity for nonlinear sub-elliptic systems with VMO-coefficients in the Heisenberg group

open access: yesAdvances in Nonlinear Analysis, 2018
We consider nonlinear sub-elliptic systems with VMO-coefficients in the Heisenberg group and prove partial Hölder continuity results for weak solutions using a generalization of the technique of 𝒜{\mathcal{A}}-harmonic approximation.

Uniqueness results for elliptic problems with singular data

open access: yesBoundary Value Problems, 2006
We obtain some uniqueness results for the Dirichlet problem for second-order elliptic equations in an unbounded open set Ω without the cone property, and with data depending on appropriate weight functions.

Optimal partial regularity of discontinuous subelliptic systems with VMO coefficients related to Hörmander’s vector fields

open access: yesBoundary Value Problems, 2023
In this paper, we study discontinuous subelliptic systems with VMO coefficients related to Hörmander’s vector fields. In the case of growth exponential p ≥ 2 $p\geq 2$  , the regularity results of the partial Hölder continuity of weak solutions are ...

Regularity results for singular elliptic problems

open access: yesJournal of Function Spaces and Applications, 2006
Some local and global regularity results for solutions of linear elliptic equations in weighted spaces are proved. Here the leading coefficients are VMO functions, while the hypotheses on the other coefficients and the boundary conditions involve a ...
