The naive iterative method for solving Au = b is to rewrite it in fixed point form u = T u + c, where T = I - A and c = b.
(a) What conditions on the eigenvalues of A ensure convergence of the naive method?
(b) Use the Gerschgorin Theorem 10.34 to prove that the nai ve method converges to the solution to
