Abstract:In this paper, we study the following nonlinear Dirac equationwhere p ∈ (2, 3), a > 0 is a constant, α = (α 1 , α 2 , α 3 ), α 1 , α 2 , α 3 and β are 4×4 Pauli-Dirac matrices. Our investigation focuses on the case in which V (x) may attain ±a at somewhere or at infinity and K (x) may approach ±∞ as x accumulating at some points and as |x| → ∞. This is a case with the potentials being singular, which has not been studied before as all the works in the literature require lim sup |x|→∞ |V (x)| < a and K ∈ L ∞ (R… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
