The new systematic procedure in group theoretic methods with applications to class of boundary layer flows

The present paper is made of the formalism of a new systematic group theoretic procedure for reducing the number of independent variables from a system of partial differential equations with the set of assigned auxiliary conditions. The present procedure has an advantage to group theoretic techniques developed in the past. The present technique is supported by an application to system of nonlinear partial differential equations governing a steady two dimensional boundary layer flow of incompressible second order fluid past a stretching sheet.
