A note on certain ergodicity coeflcients

Francesco Tudisco (2015)

Special Matrices

Similarity:

We investigate two ergodicity coefficients ɸ ∥∥ and τn−1, originally introduced to bound the subdominant eigenvalues of nonnegative matrices. The former has been generalized to complex matrices in recent years and several properties for such generalized version have been shown so far.We provide a further result concerning the limit of its powers. Then we propose a generalization of the second coefficient τ n−1 and we show that, under mild conditions, it can be used to recast the eigenvector...

A deflation formula for tridiagonal matrices

Miroslav Fiedler (1980)

Aplikace matematiky

Similarity:

An explicit formula for the deflation of a tridiagonal matrix is presented. The resulting matrix is again tridiagonal.
