Toeplitz Matrices and Commuting Tridiagonal Matrices
SIAM Journal on Matrix Analysis and Applications, 1991A new proof is presented of the existence of commuting tridiagonal matrices for a particular family of Toeplitz matrices.

Eigenvalues of tridiagonal symmetric interval matrices
IEEE Transactions on Automatic Control, 1994The paper deals with the eigenvalue problem for symmetric tridiagonal interval matrices. A method for bounding the eigenvalues is described, which uses certain ratios in the Sturm sequence. The key idea is to avoid dependent intervals in the relevant interval operations. The method requires twice as many operations as the ordinary real Sturm method and

A Parallel Preconditioner for Block Tridiagonal Matrices.
1993This paper is concerned with the solution of block tridiagonal linear algebraic systems by the preconditioned conjugate gradient (PCG) method. If we consider two splittings of the coefficient matrix, it is possible to derive a parallel additive polynomial preconditioner and to give conditions for such preconditioner to be symmetric positive definite ...
