Abstract
In this paper, two methods are used to solve a nonlocal Cauchy problem of a delay differential equation; Adomian decomposition method (ADM) and Picard method. The existence and uniqueness of the solution are proved. The convergence of the series solution and the error analysis are studied.
Keywords: Nonlocal cauchy problem, existence, uniqueness, error analysis, Adomian method, Picard method
