Connections between diagonal stability and the secant condition for cyclic systems

2006 American Control Conference, 2006
We consider a class of systems with a cyclic interconnection structure that arises, among other examples, in dynamic models for certain biochemical reactions. We first show that a "secant condition" for stability, derived earlier in the literature, is in fact a necessary and sufficient condition for diagonal stability of the corresponding class of ...

Diagonal conditions for lattice-valued uniform convergence spaces

Fuzzy Sets and Systems, 2013
We define diagonal conditions for lattice-valued uniform convergence spaces and show that these conditions are preserved under initial constructions. Further, the forgetful functor from the category of stratified lattice-valued uniform convergence spaces into the category of stratified lattice-valued limit spaces maps these conditions to corresponding ...

On diagonal N-representablity problem II: Sufficient conditions

Journal of Computational Methods in Sciences and Engineering, 2013
A set of transformational matrices (TM) is introduced which convert the weights of a mixed state into the diagonal elements of reduced density matrix (RDM). The formulae for the products of TM are deduced; the singular values of TM are calculated and the corresponding spectral expansion is built.

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.

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.

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.
