On the Role of Ill-conditioning: Biharmonic Eigenvalue Problem and Multigrid Algorithms
Very fine discretizations of differential operators often lead to large, sparse matrices A, where the condition number of A is large. Such ill-conditioning has well known effects on both solving linear systems and eigenvalue computations, and, in general, computing solutions with relative accuracy i...
