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…
