I am working with block Jacobi like preconditioners which are very cheap for my problem. But I could not find much about the dynamics of basic preconditioners (block Jacobi, Gauss-Seidel, ILU etc). Most books, including that by Saad, do not elaborate mathematically on how they converge. Can anybody suggest some classic literature on this?
