dc.description.abstract
We obtain new bounds for the entries of the inverse of a diagonally-dominant tridiagonal matrix which improve the best previous ones, due to H.-B. Li et al. We apply our bounds to the tridiagonal matrices arising in the second-order finite-difference discretization of certain boundary-value problems of parabolic type, establishing asymptotically optimal bounds.
