Title: Growth rate and existence of solutions to Dirichlet problems for prescribed mean curvature equations on unbounded domains Author: Zhiren Jin (Wichita State Univ., Kansas, USA) Abstract: We prove growth rate estimates and existence of solutions to Dirichlet problems for prescribed mean curvature equation on unbounded domains inside the complement of a cone or a parabola like region in $\mathbb{R}^n$ ($n\geq 2$). The existence results are proved using a modified Perron's method by which a subsolution is a solution to the minimal surface equation, while the role played by a supersolution is replaced by estimates on the uniform $C^{0}$ bounds on the liftings of subfunctions on compact sets.
