We prove a critical-point result which provides conditions for the existence of infinitely many critical points of a strongly indefinite functional with perturbed symmetries. Then we apply this result to obtain infinitely many solutions of non-symmet

We study the semi-classical ground states of the nonlinear Maxwell-Dirac system: \[ \left\{ \begin{aligned} &\al\cdot\big(i\hbar\nabla+ q(x)\fa(x)\big) w-a\bt w -\omega w - q(x)\phi(x) w = P(x)g(\jdz{w}) w\\ &-\Delta\phi=q(x)\jdz{w}^2\\ &-\Delta{A_k}

This unique book focuses on critical point theory for strongly indefinite functionals in order to deal with nonlinear variational problems in areas such as physics, mechanics and economics. With the original ingredients of Lipschitz partitions of uni

In the present article, we study multiplicity of semi-classical solutions of a Yukawa-coupled massive Dirac-Klein-Gordon system with the general nonlinear self-coupling, which is either subcritical or critical growth. The number of solutions obtained

We show existence and multiplicity results for nonlinear Dirac--Klein--Gordon systems with two different nonlinear interaction terms. Both the Dirac field and the Klein--Gordon field considered her...

In this paper we are interested in the existence of semiclassical states for the Choquard type equation − ε 2 Δ u + V ( x ) u = ∫ R N G ( u ( y ) ) | x − y | μ d y g ( u ) in R N , where 0 < μ < N, N ⩾ 3, ɛ is a positive parameter and G
