【 摘 要 】
In the present paper, we consider the following magnetic nonlinear Choquard equation { (-i del + A(x))(2)u + mu g(x)u = lambda u + (vertical bar x vertical bar(-alpha) * vertical bar u vertical bar(2*alpha)) vertical bar u vertical bar(2*alpha-2)u in R-n, u is an element of H-1 (R-n, C) where n >= 4, 2*(alpha) = 2n-alpha/n-2, alpha is an element of (0,n), mu > 0, lambda > 0 is a parameter, A(x) : R-n -> R-n is a magnetic vector potential and g(x) is a real valued potential function on R-n. Using variational methods, we establish the existence of least energy solution under some suitable conditions. Moreover, the concentration behavior of solutions is also studied as mu -> +infinity.
