  • Multiplicity and concentration of solutions for Kirchhoff equations with magnetic field
    Ji, Chao ; Rǎdulescu, Vicenţiu, 1958-
    In this paper, we study the following nonlinear magnetic Kirchhoff equation: ▫$$ \begin{cases} -(a\epsilon^2 + b\epsilon[u]_{A/\epsilon}^2)\Delta_{A/\epsilon}u + V(x)u = f(|u|^2)u & \text{in} ... \;\mathbb{R}^3, \\ u \in H^1(\mathbb{R}^3,\mathbb{C}), \end{cases}$$▫ where ▫$\epsilon >0$▫, ▫$a,b>0$▫ are constants, ▫$V: \mathbb{R}^{3} \rightarrow \mathbb{R}$▫ and ▫$A: \mathbb{R}^3 \rightarrow \mathbb{R}^3$▫ are continuous potentials, and ▫$\Delta_A u$▫ is the magnetic Laplace operator. Under a local assumption on the potential ▫$V$▫, by combining variational methods, a penalization technique and the Ljusternik-Schnirelmann theory, we prove multiplicity properties of solutions and concentration phenomena for ▫$\epsilon$▫ small. In this problem, the function ▫$f$▫ is only continuous, which allows to consider larger classes of nonlinearities in the reaction.
