Existence and multiplicity of solutions for fractional p-Laplacian equation involving critical concave-convex nonlinearities

Advanced Nonlinear Studies
We investigate the following fractional p-Laplacian convex-concave problem:(Pλ)(−Δ)psu=λ|u|q−2u+|u|ps*−2u inΩ,u=0 inRn\Ω,  $$\left({P}_{\lambda }\right) \begin{cases}\begin{aligned}\hfill {\left(-{\Delta}\right)}_{p}^{s}u& =\lambda \vert u{\vert

Infinitely many periodic solutions for some second-order differential systems with p(t)-Laplacian

Boundary Value Problems, 2011
In this article, we investigate the existence of infinitely many periodic solutions for some nonautonomous second-order differential systems with p(t)-Laplacian. Some multiplicity results are obtained using critical point theory.

Brake subharmonic solutions of first order Hamiltonian systems

, 2010
In this paper, we mainly use the Galerkin approximation method and the iteration inequalities of the $L$-Maslov type index theory to study the properties of brake subharmonic solutions for the first order non-autonomous Hamiltonian systems. We prove that

On a geometric equation involving the Sobolev trace critical exponent

, 2013
In this paper we consider the problem of prescribing the mean curvature on the boundary of the unit ball of Rn, n≥4. Under the assumption that the prescribed function is flat near its critical point, we give precise estimates on the losses of the ...

Existence of periodic solutions with prescribed minimal period of a 2nth-order discrete system

Open Mathematics, 2019
In this paper, we concern with a 2nth-order discrete system. Using the critical point theory, we establish various sets of sufficient conditions for the existence of periodic solutions with prescribed minimal period. To the best of our knowledge, this is
