Existence, Uniqueness, and Input-to-State Stability of Ground State Stationary Strong Solution of a Single-Species Model via Mountain Pass Lemma [PDF]
Complexity, 2021 In this study, the authors utilize mountain pass lemma, variational methods, regularization technique, and the Lyapunov function method to derive the unique existence of the positive classical stationary solution of a single-species ecosystem ...

Journal of Functional Analysis, 2005 In this paper it is proved a critical point theorem of mountain-pass type which yields a sequence of critical points converging to zero. The proof combines a pseudo-gradient property with a deformation lemma. The abstract result is applied for proving a multiplicity result for the semilinear elliptic equation \(-\Delta u=f(x,u)\) in \(\Omega\) under ...

Advances in Difference Equations, 2019 In this paper, we prove a new quantitative deformation lemma, and then gain a new mountain pass theorem in Hilbert spaces. By using the new mountain pass theorem, we obtain the new existence of two nontrivial periodic solutions for a class of nonlinear ...

LargeH-surfaces via the mountain-pass-lemma
Mathematische Annalen, 1985 L'A. considère le système \(\Delta u=2Hu_ x\wedge u_ y\) où \(B=disque\) unité de \({\mathbb{R}}^ 2\) avec condition de Dirichlet ou condition de Plateau. L'énergie associée à ce système est \(E(u)=(1/2)\int | \nabla u|^ 2+(2H/3)\int u\circ u_ x\bigwedge u_ x\). L'A. montre que si E admet un minimum local \b{u}, alors il existe une deuxième solution \(\

Symmetric mountain pass lemma and sublinear elliptic equations
Journal of Differential Equations, 2016 This paper deals with the qualitative analysis of solutions of a class of quasilinear elliptic equations with Dirichlet zero boundary condition. The main result of this paper establishes a necessary and sufficient condition such that the zero solution is an accumulation point of the set of all solutions.

Some extensions of the mountain pass lemma
Differential and Integral Equations, 1988 This article deals with some variants of the classical mountain pass lemma. In the first part the following result is obtained: if \(f: \mathbb{E}\to\mathbb{R}\) is a \(C^ 1\) smooth functional with \(PS\)-condition on a real Banach space \(\mathbb{E}\), \(x_ 0,x_ 1\in\mathbb{E}\), \({\mathcal D}\) is an open neighborhood, \(x_ 0,x_ 1\not\in{\mathcal D}

ON A NEW FIXED POINT THEOREM ON HILBERT SPACES VIA THE MOUNTAIN PASS LEMMA AND APPLICATIONS TO ELLIPTIC BOUNDARY VALUE PROBLEMS [PDF]
International Journal of Pure and Applied Mathematics, 2016 In this paper we present a new fixed point theorem in Hilbert spaces. Using a suitable critical point theorem we provide conditions under which potential operators have a fixed point. An application is given to illustrate the theory.
