open access: yesJournal of Function Spaces, Volume 2024, Issue 1, 2024.
In this paper, we consider the weighted m‐biharmonic equation with nonlinear damping and source terms. We proved the global existence of solutions. Later, the decay of the energy is established by using Nakao’s inequality. Finally, we proved the blow‐up of solutions in finite time.

Multiplicity of Solutions for a Class of Kirchhoff–Poisson Type Problem

open access: yesAbstract and Applied Analysis, Volume 2024, Issue 1, 2024.
In this paper, we use the fountain theorems to investigate a class of nonlinear Kirchhoff–Poisson type problem. When the nonlinearity f satisfies the Ambrosetti–Rabinowitz’s 4‐superlinearity condition, or under some weaker superlinearity condition, we establish two theorems concerning with the existence of infinitely many solutions.
