Abstract In this paper, a semipositone anisotropic p-Laplacian problem − Δ p → u = λ f ( u ) , $$ -\Delta _{\overrightarrow{p}}u=\lambda f(u), $$ on a bounded domain with the Dirchlet boundary condition is considered, where A ( u q − 1 ) ≤

Abstract Here, the existence and multiplicity of weak solutions to a generalized ( p ( ⋅ ) , q ( ⋅ ) ) $(p(\cdot ),q(\cdot ))$ -Laplace equation involving Leray–Lions type operators with Hardy potential are studied under Dirichlet boundary cond

Abstract We study the existence of multiple solutions to a nonlocal system involving fourth order Leray–Lions type operators along with singular terms under Navier boundary conditions. The method is based on the variational methods.

Abstract In this paper, a nonhomogeneous elliptic equation of the form − A ( x , | u | L r ( x ) ) div ( a ( | ∇ u | p ( x ) ) | ∇ u | p ( x ) − 2 ∇ u ) = f ( x , u ) | ∇ u | L q ( x ) α ( x ) + g ( x , u ) | ∇ u | L s ( x ) γ ( x ) $

Abstract In this paper, we study some results on the existence and multiplicity of solutions for a class of nonlocal quasilinear elliptic systems. In fact, we prove the existence of precise intervals of positive parameters such that the problem admit

Abstract Here, a nonlocal nonlinear operator known as the fractional ( p , q ) $(p,q)$ -Laplacian is considered. The existence of a mountain pass solution is proved via critical point theory and variational methods. To this aim, the well-known theore
