Multiplicity and concentration of semi-classical solutions to nonlinear Dirac-Klein-Gordon systems
Abstract 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 is described by the ratio of maximum and behavior at infinity of the potentials. We use …
