The paper deals with a cascadic conjugate-gradient method (shortly called the CCCalgorithm) which was proposed by P. Deufihard and can be considered as a simpler version of a multigrid (multilevel) method. We define it recurrently for discrete self-adjoint positive-definite problems on a sequence of
## Abstract This paper is concerned with proving theoretical results related to the convergence of the conjugate gradient (CG) method for solving positive definite symmetric linear systems. Considering the inverse of the projection of the inverse of the matrix, new relations for ratios of the __A__
