We establish upper and lower bounds for the entries of the inverses of diagonally dominant tridiagonal matrices. These bounds improve the bounds recently given by Shivakumar and Ji. Moreover, we show how to improve our bounds iteratively. For an n x n M-matrix this iterative refinement yields the ex
The eigenvalues of the radial Schr6dinger equation are calculated very accurately by obtaining exact upper and lower bounds. By truncating the usual unbounded domain [0,cx~) of the system to a finite interval of the form [0,g], two auxiliary eigenvalue problems are defined. It is then proved that th
