Nonlinear Equations Involving Nonpositive Definite Linear Operators via Variational Methods

Journal of Integral Equations and Applications, 2007
The paper is concerned with the application of variational methods, namely the variational method due to \textit{B. Ricceri} [J. Comput. Appl. Math. 113, No. 1--2, 401--410 (2000; Zbl 0946.49001)] in showing the existence of solutions for nonlinear equations of the type \(u=K\mathbf{f}(u)\), where \(K:L^{q_{0}}( \Omega) \rightarrow L^{p_{0}}( \Omega) \)

A modification fractional variational iteration method for solving nonlinear gas dynamic and coupled KdV equations involving local fractional operators

Thermal Science, 2018
In this paper, we apply a new technique, namely local fractional variational iteration transform method on homogeneous/non-homogeneous non-linear gas dynamic and coupled KdV equations to obtain the analytical approximate solutions. The iteration procedure is based on local fractional derivative and integral operators.

Normalized Solutions for an Anisotropic Nonlinear Schrödinger Equation with Potentials

Fractal and Fractional
In this paper, we study the existence of normalized solutions for anisotropic nonlinear Schrödinger equation with potentials which are bounded and converge to positive constants at infinity.

Existence results for Robin problems involving p(x)-Laplacian-like operators with convection term

Demonstratio Mathematica
This paper studies the existence of solutions for Robin problems involving p(x)-Laplacian-like operators which arise from capillarity phenomena. When we only consider the convective term, due to the lack of a variational structure, the well-known ...

Infinitely many solutions for a Neumann elliptic system with ( p ( ⋅ ) , q ( ⋅ ) ) $(p(\cdot ), q(\cdot ))$ -Laplacian type operator

Boundary Value Problems
This paper is concerned with a system of nonlinear elliptic equations driven by ( p ( ⋅ ) , q ( ⋅ ) ) $(p(\cdot ), q(\cdot ))$ -Laplacian type operators with variable exponents, subject to homogeneous Neumann boundary conditions.

Combined effects and degenerate phenomena in nonlinear stationary problems

Le Matematiche, 2010
In this survey paper we are concerned with several nonlinear stationary problems involving nonhomogeneous differential operators. We report on some recent qualitative results related with various nonlinear problems in Orlicz-Sobolev spaces.
