Abstract :This communication deals with the analytical solutions of Cauchy problem for Cauchy-Riemann system of equations which is basically unstable according to Hadamard but its solution exists if its initial data is analytic. Here we used the Vectorial Adomian Decomposition insert ignore into journalissuearticles values(VAD); method, Vectorial Variational Iteration insert ignore into journalissuearticles values(VVI); method, and Vectorial Modified Picard’s Method insert ignore into journalissuearticles values(VMP); method to get the convergent series solution. These suggested schemes give analytical approximation in an infinite series form without using discretization. These methods are effectual and reliable which is demonstrated through six model problems having variety of source terms and analytic initial data.
