Hölder regularity and Harnack inequality for the logarithmic Laplacian

Anup Biswas, Subhajit Roy, Aniket Sen +1

In this article, we establish Schauder-type estimates for the logarithmic Laplacian. We show that for a -Hölder inhomogeneous term, the solution is also -Hölder in the interi…

On Coron problems with Choquard term and mixed operator

Jacques Giacomoni, Tuhina Mukherjee, Lovelesh Sharma

In this article, we study a Coron-type problem involving a critical Choquard nonlinearity driven by a mixed operator combining the Laplacian and fractional Laplacian. In annular-ty…

The role of the mean curvature in nonlinear p-Laplacian problems with critical exponent

Hichem Chtioui, Hichem Hajaiej, Lovelesh Sharma

We deal with critical nonlinear problems involving the p-Laplacian operator on bounded domains with mixed boundary conditions. We prove the existence of least energy solutions. Our…

Spectrum properties of mixed operators under the mixed boundary conditions

Lovelesh Sharma

In this paper, we describe the spectrum properties of mixed operators, precisely the superposition of the classical Laplace operator and the fractional Laplace operator in the pres…

The effect of boundary geometry in nonlocal critical problems with Hardy-Littlewood-Sobolev exponent

Hichem Chtioui, Tuhina Mukherjee, Lovelesh Sharma

In this paper we consider a mixed Dirichlet-Neumann boundary value problem. lem involving Choquard nonlinearity with upper critical exponent in the sense of Hardy- Littlewood Sobol…

On singular problems associated with mixed operators under mixed boundary conditions

Tuhina Mukherjee, Lovelesh Sharma

In this paper, we study the following singular problem associated with mixed operators (the combination of the classical Laplace operator and the fractional Laplace operator) under…
