Abstract:We study the existence of spacelike graphs for the prescribed mean curvature equation in the Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime. By using a conformal change of variable, this problem is translated into an equivalent problem in the Lorentz-Minkowski spacetime. Then, by using Rabinowitz's global bifurcation method, we obtain the existence and multiplicity of positive solutions for this equation with 0-Dirichlet boundary condition on a ball. Moreover, the global structure of the positive solution set is studied. (C) 2018 Elsevier Inc. All rights reserved.
