| Abstract: | Existence and uniqueness of global solutions for a one-phase Stefan problem are proved in this paper.The author firstly translates the Stefan problem into an equivalent system of integral equations with the help of Green Identity and has the existence and uniqueness of local solutions to the integral equations by contraction mapping theorem,then applies the continuation method to get the existence and uniqueness of global solutions. |
