Three solutions for a Navier boundary value problem involving the -biharmonic

Infinitely many solutions for a nonlinear Navier boundary systems involving $(p(x),q(x))$-biharmonic

“…Combining (4.6), (4.9) and (4.10), we obtain 11) for n large enough, so lim Let (b n ) be a sequence of positive numbers such that b n → 0 + and…”

“…The investigation of existence and multiplicity of solutions for problems involving biharmonic, p-biharmonic and p(x)-biharmonic operators has drawn the attention of many authors, see [2,3,5,6,11] and references therein. Candito and Livrea [5] considered the nonlinear elliptic Navier boundary-value problem ∆(|∆u| p−2 ∆u) = λf (x, u) in Ω,…”

“…In recent years, many authors considered the existence and multiplicity of solutions for some fourth order problems [1][2][3][4][5][6][7][8][9][10]. In [4], based on critical point theory, the existence of infinitely many solutions has been established for a class of nonlinear elliptic equations involving the -biharmonic operator and under Navier boundary value conditions.…”

Existence of non-trivial solutions for systems of n fourth order partial differential equations

“…Many authors have studied the existence of at least one solution, or multiple solutions, or even infinitely many solutions for fourth-order boundary value problems by using lower and upper solution methods, Morse theory, the mountain-pass theorem, constrained minimization and concentration-compactness principle, fixed-point theorems and degree theory, and critical point theory and variational methods, and we refer the reader to the papers [2,[4][5][6][7][8][9][10][11] and references therein.…”
