STAGNATION IN THE RITZ AND GALYORKIN METHODS.

Ritz and Galerkin methods play an important role in variational and auxiliary methods. This is the case in Ritz and Galyorkin’s articles on defining stagnation conditions with the help of examples. Ritz and Galyorkin prove that the project is equal to each other. This article examines the stationarity of the Ritz and Galyorkin methods for the Poisson’s equation.
