Nonlinear differential equations and algebraic systemsDOI: 10.1155/s0161171278000290 Keywords: Riccati equations , Abel equations , Cauchy-Kowalewski theorem , Cauchy-Kowalewski system , universal Cauchy-Kowalewski system. Abstract: In this paper we obtain the general solution of scalar, first-order differential equations. The method is variation of parameters with asymptotic series and the theory of partial differential equations.
