On relation between P-matrices and regularity of interval matrices

We explore new results between P-matrix property and regularity of interval matrices. In particular, we show that an interval matrix is regular in and only if some also investigate the converse direction. We reduce the prob...

On Rump?s characterization of P-matrices

The necessary and sufficient P-matrix condition by Rump (Linear Algebra Appl 363:237?250, 2003) is simplified by showing that one of its assumptions can be deleted without affecting validity of the result....

On constants in the Füredi-Hajnal and the Stanley-Wilf conjecture

For a given permutation matrix P, let f_P(n) be the maximum number of 1-entries in an nxn (0,1)-matrix avoiding P and let S_P(n) be the set of all nxn permutation^(const^(klog(k)))to s(P){=const^(klog(k)) ...

Better upper bounds on the Füredi-Hajnal limits of permutations

Enclosing the solution set of the parametric generalised Sylvester matrix equation A(p)XB(p) plus C(p)XD(p) = F(p)

In this paper, we investigate the parametric generalised Sylvester matrix equation , whose elements are linear functions of uncertain parameters varying within intervals. This model generalises both interval matrix equations and par...

Linear matrix inequalities for robust strictly positive real design.

A necessary and sufficient condition is proposed for the existence of a polynomial p(s) such that the rational function p(s)/q(s) is robustly strictly positive out that thewhole set of candidates p(s) is a convex subset of ...
