Critical Concave Convex Ambrosetti–Prodi Type Problems for Fractional 𝑝-Laplacian

open access: yesAdvanced Nonlinear Studies, 2020
In this paper, we consider a class of critical concave convex Ambrosetti–Prodi type problems involving the fractional p-Laplacian operator. By applying the linking theorem and the mountain pass theorem as well, the interaction of the nonlinearities with ...

Bäcklund transformations for several cases of a type of generalized KdV equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 63, Page 3369-3377, 2004., 2004
An alternate generalized Korteweg‐de Vries system is studied here. A procedure for generating solutions is given. A theorem is presented, which is subsequently applied to this equation to obtain a type of Bäcklund transformation for several specific cases of the power of the derivative term appearing in the equation. In the process, several interesting,

Variational approach to dynamics of bright solitons in lossy optical fibers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 49, Page 3143-3148, 2003., 2003
A variational analysis of dynamics of soliton solution of coupled nonlinear Schrödinger equations with oscillating terms is made, considering a birefringent fiber with a third‐order nonlinearity in the anomalous dispersion frequency region. This theoretical model predicts optical soliton oscillations in lossy fibers.

Eigenfrequencies of generally restrained beams

open access: yesJournal of Applied Mathematics, Volume 2003, Issue 10, Page 503-516, 2003., 2003
We deal with the exact determination of eigenfrequencies of a beam with intermediate elastic constraints and generally restrained ends. It is the purpose of this paper to use the calculus of variations to obtain the equations of motion and the natural boundary conditions, and particularly those at the intermediate constraints.

Perturbations near resonance for the p‐Laplacian in ℝN

open access: yesAbstract and Applied Analysis, Volume 7, Issue 6, Page 323-334, 2002., 2002
We study a multiplicity result for the perturbed p‐Laplacian equation −Δpu − λg(x)|u|p−2u = f(x, u) + h(x) in ℝN, where 1 < p < N and λ is near λ 1, the principal eigenvalue of the weighted eigenvalue problem −Δpu = λg(x)|u|p−2u in ℝN. Depending on which side λ is from λ 1, we prove the existence of one or three solutions.

On the location of the peaks of least‐energy solutions to semilinear Dirichlet problems with critical growth

open access: yesAbstract and Applied Analysis, Volume 7, Issue 10, Page 547-561, 2002., 2002
We study the location of the peaks of solution for the critical growth problem −ε 2Δu+u=f(u)+u 2*−1, u > 0 in Ω, u = 0 on ∂Ω, where Ω is a bounded domain; 2* = 2N/(N − 2), N ≥ 3, is the critical Sobolev exponent and f has a behavior like up, 1 < p < 2* − 1.

Higher-order Mechanics: Variational Principles and other topics [PDF]

open access: yes, 2012
After reviewing the Lagrangian-Hamiltonian unified formalism (i.e, the Skinner-Rusk formalism) for higher-order (non-autonomous) dynamical systems, we state a unified geometrical version of the Variational Principles which allows us to derive the ...

Multiple solutions for a problem with resonance involving the p‐Laplacian

open access: yesAbstract and Applied Analysis, Volume 3, Issue 1-2, Page 191-201, 1998., 1998
In this paper we will investigate the existence of multiple solutions for the problem where Δpu = div(|∇u|p−2∇u) is the p‐Laplacian operator, Ω⫅ℝN is a bounded domain with smooth boundary, h and g are bounded functions, N ≥ 1 and 1 < p < ∞. Using the Mountain Pass Theorem and the Ekeland Variational Principle, we will show the existence of at least ...
