Solutions to an anisotropic system via sub-supersolution method and Mountain Pass Theorem
Electronic Journal of Qualitative Theory of Differential Equations, 2019 Summary: We use sub-supersolution method and Mountain Pass Theorem in order to show existence and multiplicity of solution for quasilinear system given by \[-\Big[\displaystyle\sum^{N}_{i=1}\frac{\partial}{\partial x_{i}}\Big \vert \frac{\partial u}{\partial x_{i}} \Big\vert^{p_{i}-2}\frac{\partial u}{\partial x_{i}}\Big] = a_{1}(x)u+ F_{u}(x,u,v) \,\,\

Harmonic balls in Liouville quantum gravity
Proceedings of the London Mathematical Society, Volume 130, Issue 1, January 2025.Abstract Harmonic balls are domains that satisfy the mean‐value property for harmonic functions. We establish the existence and uniqueness of harmonic balls on Liouville quantum gravity (LQG) surfaces using the obstacle problem formulation of Hele–Shaw flow.

Existence and comparison results for variational-hemivariational inequalities
Journal of Inequalities and Applications, 2005 We consider a prototype of quasilinear elliptic variational-hemivariational inequalities involving the indicator function of some closed convex set and a locally Lipschitz functional.

Double phase elliptic inclusions with convection and logarithmic perturbed terms
Bulletin of Mathematical SciencesThis paper deals with a new double phase elliptic inclusion (DPEI) formulated by a double phase partial differential operator with logarithmic perturbation, a general multivalued convection term defined in the domain and a general multivalued term ...

Existence results for a class of Kirchhoff type systems with Caffarelli-Kohn-Nirenberg exponents
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 This paper is concerned with the existence of positive solutions for a class of infinite semipositone kirchhoff type systems with singular weights. Our aim is to establish the existence of positive solution for λ large enough.

Multiple solutions of nonlinear fractional elliptic equations via Morse theory
Electronic Journal of Differential Equations, 2017 This article concerns the existence and multiplicity of weak solutions of the nonlinear fractional elliptic problem. We extend some well known results of semilinear Laplacian equations to the nonlocal fractional setting. Using the variational methods

Existence and multiplicity of solutions to superlinear periodic parabolic problems
Electronic Journal of Differential Equations, 2018 Let $\Omega\subset\mathbb{R}^{N}$ be a smooth bounded domain and let a,b,c be three (possibly discontinuous and unbounded) T-periodic functions with $c\geq0$.

The sub-supersolution method for Kirchhoff systems: applications
, 2016 In this paper we prove that the sub-supersolution method works for general Kirchhoff systems. We apply the cited method to prove the existence of positive solutions for some specific models.
