We consider a one-dimensional integral inequality of Moser type: set $$\begin{aligned} \quad J_c(v) = \int _{0}^1 {\textrm{e}}^{c(s) v^2(s)} ds \quad \quad \hbox { and consider } \quad \quad \sup _{ \{\int _0^1 |v'|^2 = 1, v(0) = 0\}} J_c(v) \end{ali

We establish the existence and multiplicity of solutions for a Kirchhoff-type problem in $$\mathbb R^4$$ involving a critical and concave–convex nonlinearity. Since in dimension four, the Sobolev critical exponent is $$2^*=4$$ , there is a tie betw

We discuss the existence, nonexistence and multiplicity of solutions for a class of elliptic equations in the unit ball with zero Dirichlet boundary conditions involving nonlinearities with supercritical growth. By using Pohozaev type identity we pro

We establish the existence of two nontrivial solutions to semilinear elliptic systems with superquadratic and subcritical growth rates. For a small positive parameter $ lambda $, we consider the system $$displaylines{ -Delta v = lambda f(u) quad hbox

In this paper we use variational techniques to give existence results for the problem { S k [ u ] = f ( x , − u ) in Ω u 0 in Ω u = 0 on ∂ Ω where S k [ u ] is the k-Hessian operator and f ( x , u ) is a supercritical nonlinearity in the sense

Using mainly variational methods and an approximation technique we obtain one homoclinic orbit for a Hamiltonian system type (P) u + V u ( t , u ) = 0 . Our approach allows us to consider new examples of nonlinearities which do not satisfy the classi
