On the regularity theory for mixed local and nonlocal weighted quasilinear elliptic equations

Sanjit Biswas, Prashanta Garain

We investigate a broad class of mixed local and nonlocal degenerate -Laplace equations with general right-hand sides. The degeneracy is governed by Muckenhoupt -weights, yi…

Symmetry and Approximate Symmetry for Solutions of Mixed Local-Nonlocal Singular Equations

Sanjit Biswas

In this article, we establish radial symmetry for positive weak solutions of a class of mixed local-nonlocal equations with possibly singular nonlinearity via the moving plane meth…

Existence Theory for a class of semilinear mixed local and nonlocal equations involving variable singularities and singular measures

Sanjit Biswas, Prashanta Garain

This article establishes the existence of weak solutions for a class of mixed local-nonlocal problems with pure and perturbed singular nonlinearities. A key novelty is the treatmen…

Multiplicity results for mixed local-nonlocal equations with singular and critical exponential nonlinearity in R^2

Sanjit Biswas

In this article, we prove the existence of at least two positive weak solutions for a mixed local-nonlocal singular problem in the presence of critical exponential nonlinearity in…

Regularity and existence for semilinear mixed local-nonlocal equations with variable singularities and measure data

Sanjit Biswas, Prashanta Garain

This article proves the existence and regularity of weak solutions for a class of mixed local-nonlocal problems with singular nonlinearities. We examine both the purely singular pr…
