(Elsevier, 2016)We study existence and uniqueness of weak solutions to (F) partial derivative(t)u+(-Delta)(alpha)u+h(t, u) = 0 in (0,infinity) xR(N), with initial condition u(0, center dot) -nu in R-N, where N >= 2, the operator (-Delta)(alpha) ...

(Elsevier, 2018)In this paper, we study the elliptic problem with Dirac mass { -Delta u = Vu(p) + k delta(0) in R-N, (1) lim(vertical bar x vertical bar ->+infinity) u(x) = 0, where N > 2, p > 0, k > 0, delta(0) is the Dirac ...
