Using the classical Banach fixed point theorem, we propose a novel method to obtain existence and uniqueness result pertaining to the solutions of semilinear elliptic partial differential equation of the type Δ u+ f(x, u, Du) = 0 , in Ω ⊂ R n and u| ∂ Ω = 0 , in a suitable Sobolev space. Here f:Ω×R×Rn→R is either a linear or a non-linear Lipshitz continuous function. The approach attempted here can be used as an algorithm by the numerical analysts to determine a solution to a partial differential equation of the above type. © 2016, Springer India Pvt. Ltd.
