In this article, we mainly study the global existence of multiple positive solutions for the logarithmic Schrödinger equation with a Coulomb type potential

Δu+V(ϵx)u=λ(Iα|u|p)|u|p1+ulogu2inR3,

where uH1(R3), ϵ>0, V is a continuous function with a global minimum, and Coulomb type energies with 0<α<3 and p1. We explore the existence of local positive solutions without the functional having to be a combination of a C1 functional and a convex semicontinuous functional, as is required in the global case.
