Nonlinear Dirac equations on noncompact quantum graphs with potentials: Multiplicity and Concentration

Guangze Gu, Ziwei Li, Michael Ruzhansky +1

In this paper, we study the existence and multiplicity of solutions to the following class of nonlinear Dirac equations (NLDE) on noncompact quantum graphs: \[ -i\,\varepsilon c\,Ï…
