Le « Mountain Pass Theorem »

, 2022
The "sente" (Latin semita, from se- (“apart”) and from the radical *mi, from meo (“to go”) has more to do with the weft, the crossroads, than with feeling or sensations.

Infinitely many homoclinic solutions for a class of nonlinear difference equations

Electronic Journal of Qualitative Theory of Differential Equations, 2012
By using the Symmetric Mountain Pass Theorem, we establish some existence criteria to guarantee a class of nonlinear difference equation has infinitely many homoclinic orbits. Our conditions on the nonlinear term are rather relaxed and we generalize some

Existence of Multiple Solutions for a Class of Biharmonic Equations

Discrete Dynamics in Nature and Society, 2013
By a symmetric Mountain Pass Theorem, a class of biharmonic equations with Navier type boundary value at the resonant and nonresonant case are discussed, and infinitely many solutions of the equations are obtained.

Multiple Solutions for Second-Order Sturm–Liouville Boundary Value Problems with Subquadratic Potentials at Zero

Journal of Mathematics, 2021
We deal with the following Sturm–Liouville boundary value problem: −Ptx′t′+Btxt=λ∇xVt,x,  a.e. t∈0,1x0cos  α−P0x′0sin  α=0x1cos  β−P1x′1sin  β=0 Under the subquadratic condition at zero, we obtain the existence of two nontrivial solutions and infinitely ...

Multiplicity of solutions for quasilinear elliptic problems involving $\Phi$-Laplacian operator and critical growth

Electronic Journal of Qualitative Theory of Differential Equations, 2019
In this paper, we study a class of quasilinear elliptic equations with $\Phi$-Laplacian operator and critical growth. Using the symmetric mountain pass theorem and the concentration-compactness principle, we demonstrate that there exists $\lambda_i>0 ...
