Existence of multiple solutions for quasilinear diagonal elliptic systems
Electronic Journal of Differential Equations, 1999 Nonsmooth-critical-point theory is applied in proving multiplicity results for the quasilinear symmetric elliptic system $$ -sum_{i,j=1}^{n}D_j(a^{k}_{ij}(x,u)D_iu_k)+ {1over 2}sum_{i,j=1}^{n}sum_{h=1}^N D_{s_k}a^{h}_{ij}(x,u)D_iu_hD_ju_h=g_k(x,u ...

Study on Quantum Approximation Optimization Algorithm in Airport Cargo Transportation Problem
Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.The vehicle routing problem (VRP) is a core NP‐hard combinatorial optimization problem in logistics and supply chain management. Quantum computing, particularly the Quantum Approximate Optimization Algorithm (QAOA), is being explored as a promising heuristic tool for tackling such problems.

On gamma-convergence for problems of jumping type
Electronic Journal of Differential Equations, 2003 The convergence of critical values for a sequence of functionals $(f_h)$ $Gamma$-converging to a functional $f_{infty}$ is studied. These functionals are related to a classical ``jumping problem'', in which the position of two real parameters $alpha,eta$

Existence and multiplicity of solutions for the noncoercive Neumann p-Laplacian
Electronic Journal of Differential Equations, 2010 We consider a nonlinear Neumann problem driven by the p-Laplacian differential operator with a nonsmooth potential (hemivariational inequality). Using variational techniques based on the smooth critical point theory and the second deformation theorem,

Three nontrivial solutions for nonlocal anisotropic inclusions under nonresonance
Electronic Journal of Differential Equations, 2019 In this article, we study a pseudo-differential inclusion driven by a nonlocal anisotropic operator and a Clarke generalized subdifferential of a nonsmooth potential, which satisfies nonresonance conditions both at the origin and at infinity. We prove

Variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition
Le Matematiche, 2010 The aim of this paper is the study of variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition. Sufficient conditions for the existence of a whole sequence of solutions which is either unbounded or converges to zero are ...
