In this paper, we study the solution theory in the Sobolev space for the nonlinear differential equation: with given initial values . By assuming that function and is continuous with respect to where and , we prove that this problem admits a solution in space and the solution is absolutely stable in the -norm. Moreover, if satisfies the Lipschitz condition on variable , then the solution is unique. Our unique existence conditions allow that is nonsmooth or discontinuous for . Several examples are provided to illustrate our theoretical analysis.
