The Van Hove diagonality conditions and ensemble averages

Physica, 1966
Abstract It is shown that a stationary, ergodic stochastic process satisfies conditions analogous to Van Hove's1) well known diagonality conditions. In this context Van Hove's irreducible diagonal matrix elements are shown to be simply cumulant averages.

Strict Diagonal Dominance and Optimal Bounds for the Skeel Condition Number

SIAM Journal on Numerical Analysis, 2007
An optimal bound for the Skeel condition number of a triangular matrix strictly diagonally dominant by rows is obtained. (A correction to the this article has been appended at the end of the pdf file.)

The Condition Number of Equivalence Transformations That Block Diagonalize Matrix Pencils

SIAM Journal on Numerical Analysis, 1983
How ill-conditioned must a matrix S be if its columns are constrained to span certain subspaces? We answer this question in order to find nearly best conditioned matrices SR and SL that block diagonalize a given matrix pencil T=A+λB, i.e. S L −1 TSR=Θ is bloc diagonal.

Criteria Conditions for Generalized Strictly Diagonally Dominant Matrices

2011
Several determination criterions for generalized strictly diagonally dominant matrix are put forward in this chapter, improving the existing correlative conclusions, extending the determination criterions for generalized strictly diagonally dominant matrix.

Bases of convergence and diagonal conditions

2012
Per le strutture di convergenza (di successioni ordina¬rie) si confrontano quattro condizioni di tipo diagonale; si costruisce un esempio di convergenza che, aggiunto alle implicazioni già note, dimostra che le quattro condizioni sono a due a due non equivalenti.

Fischer's Diagonal Condition for Lattice-Valued Convergence Spaces

Quaestiones Mathematicae, 2008
We study a generalization of a diagonal condition which classically ensures that a convergence space is topological. We show that only under an additional condition, which classically is always true, the validity of this diagonal condition implies that a Heyting algebra-valued convergence space is L-topological.

A Riccati equation for block-diagonalization of ill-conditioned systems

IEEE Transactions on Automatic Control, 1975
A simple transformation, originally introduced for singularly perturbed systems, is now applicable to a larger class of time-invariant systems.
