This paper is concerned with a class of fractional \(p(x,y)-\)Kirchhoff type problems with Dirichlet boundary data along with indefinite weight of the following form \begin{equation*} \left\lbrace\begin{array}{ll} M\left(\int_{Q}\frac{1}{p(x,y)}\f

In this paper, based on variational methods and critical point theory, we guarantee the existence of infinitely many classical solutions for a two-point boundary value problem with fourth-order Sturm-Liouville equation; Some recent results are improv

In the present work, we investigate an interval of real parameters $ \lambda $ for which the problem admits at least one nontrivial solution. Moreover we deal with the existence results of three solutions for anisotropic problems with variable expone

We investigate the existence of a weak nontrivial solution for the following problem. Our analysis is generally bathed on discussions of variational based on the Mountain Pass theorem and some recent theories one the generalized Lebesgue-Sobolev spac

The aim of this paper is to obtain three weak solutions for the Dirichlet quasilinear elliptic systems on a bonded domain. Our technical approach is based on the general three critical points theorem obtained by Ricceri.

In this paper, we investigate the existence of three generalized solutions for fourth-order Kirchhoff-type problems with a perturbed nonlinear term depending on two real parameters. Our approach is based on variational methods.

Using a variational approach, we prove the existence of solutions for the degenerate quasilinear elliptic system $$displaylines{ -hbox{div}(u_1 (x)|abla u|^{p-2} abla u) =lambda F_u(x,u,v)+mu G_u(x,u,v),cr -hbox{div}(u_2 (x)|abla v|^{q-2} abla v) =la

In this note, we establish the existence of two intervals of positive real parameters $lambda$ for which the boundary-value problem of Kirchhoff-type $$displaylines{ -Kig(int_{a}^b |u'(x)|^2dxig)u''=lambda f(x,u),cr u(a)=u(b)=0 }$$ admits three weak

In this paper, we establish an equivalent statement to minimax inequality for a special class of functionals. As an application, we prove the existence of three solutions to the Dirichlet problem $$displaylines{ -u''(x)+m(x)u(x) =lambda f(x,u(x)),qua
