Rectifiability, finite Hausdorff measure, and compactness for non‐minimizing Bernoulli free boundaries

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 3, Page 545-591, March 2025.
Abstract While there are numerous results on minimizers or stable solutions of the Bernoulli problem proving regularity of the free boundary and analyzing singularities, much less is known about critical points of the corresponding energy. Saddle points of the energy (or of closely related energies) and solutions of the corresponding time‐dependent ...

Viscosity solutions to parabolic complex Monge-Amp\`ere equations

open access: yes, 2019
In this paper, we study the Cauchy-Dirichlet problem for Parabolic complex Monge-Amp\`ere equations on a strongly pseudoconvex domain by the viscosity method. We extend the results in [EGZ15b] on the existence of solution and the convergence at infinity.

A nonlinear characterization of stochastic completeness of graphs

open access: yesMathematische Nachrichten, Volume 298, Issue 3, Page 925-943, March 2025.
Abstract We study nonlinear Schrödinger operators on graphs. We construct minimal nonnegative solutions to corresponding semilinear elliptic equations and use them to introduce the notion of stochastic completeness at infinity in a nonlinear setting. We provide characterizations for this property in terms of a semilinear Liouville theorem.

Sharp Liouville results for fully nonlinear equations with power-growth nonlinearities [PDF]

open access: yes, 2010
We study fully nonlinear elliptic equations such as \[ F(D^2u) = u^p, \quad p>1, \] in $\R^n$ or in exterior domains, where $F$ is any uniformly elliptic, positively homogeneous operator.

Optimal consumption problem in the Vasicek model [PDF]

open access: yesOpuscula Mathematica, 2015
We consider the problem of an optimal consumption strategy on the infinite time horizon based on the hyperbolic absolute risk aversion utility when the interest rate is an Ornstein-Uhlenbeck process.

Asymptotic growth rate of solutions to level‐set forced mean curvature flows with evolving spirals

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 3, Page 748-770, March 2025.
Abstract Here, we study a level‐set forced mean curvature flow with evolving spirals and the homogeneous Neumann boundary condition, which appears in a crystal growth model. Under some appropriate conditions on the forcing term, we prove that the solution is globally Lipschitz.

Ambrosetti-Prodi type results in a system of second and fourth-order ordinary differential equations

open access: yesElectronic Journal of Differential Equations, 2008
In this paper, by the variational method, we study the existence, nonexistence, and multiplicity of solutions of an Ambrosetti-Prodi type problem for a system of second and fourth order ordinary differential equations.

Minimal supersolutions of BSDEs under volatility uncertainty

open access: yesStochastic Processes and their Applications, 2015
We study the existence of minimal supersolutions of BSDEs under a family of mutually singular probability measures. We consider generators that are jointly lower semicontinuous, positive, and either convex in the control variable and monotone in the value variable, or that fulfill a specific normalization property.

Swin2‐MoSE: A new single image supersolution model for remote sensing

open access: yesIET Image Processing, Volume 19, Issue 1, January/December 2025.
In this paper, we propose Swin2‐MoSE model, an enhanced version of Swin2SR, for Remote‐Sensing Single‐Image Super‐Resolution. Our model introduces MoE‐SM, an enhanced Mixture‐of‐Experts (MoE) to replace the Feed‐Forward inside all Transformer block. MoE‐SM is designed with Smart‐Merger, and new layer for merging the output of individual experts, and ...

Existence of solutions to p-Laplace equations with logarithmic nonlinearity

open access: yesElectronic Journal of Differential Equations, 2009
This article concerns the the nonlinear elliptic equation $$ -hbox{div}(| abla u|^{p-2} abla u) =log u^{p-1}+lambda f(x,u) $$ in a bounded domain $Omega subset mathbb{R}^{N}$ with $Ngeq 1$ and $u=0$ on $partialOmega$.
