On polyharmonic Kirchhoff double phase problems without AR-conditions

Ashutosh Dixit, Tuhina Mukherjee

In this paper, we study a class of polyharmonic Kirchhoff problems driven by a double phase operator. The reaction term has subcritical growth but does not satisfy the Ambrosetti--…

On doubly critical polyharmonic double phase problems: Existence and non-existence of solutions

Ashutosh Dixit, Tuhina Mukherjee

In this article, we investigate the existence and nonexistence of weak solutions to higher-order doubly critical elliptic problems with weights, driven by a polyharmonic double pha…

Spectral Properties of the Logarithmic Laplacian with Indefinite Weights

Rakesh Arora, Tuhina Mukherjee, Arshi Vaishnavi

In this paper, we investigate a weighted eigenvalue problem driven by the Logarithmic Laplacian with indefinite weights. We prove the existence of an unbounded sequence of Lusterni…

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…

On the Fučík spectrum of the Logarithmic Laplacian

Rakesh Arora, Tuhina Mukherjee

In this paper, we investigate the Fučík spectrum associated with the logarithmic Laplacian. This spectrum is defined as the set of all pairs for…

Non variational type critical growth nonlocal system

Ashutosh Dixit, Hichem Hajaiej, Tuhina Mukherjee

This study investigates the existence, uniqueness, and multiplicity of positive solutions for a system of fractional differential equations given by: \begin{equation*} (-Δ)^{s_i}…
