A note on the matrix valued q-d algorithm and matrix orthogonal polynomials on [0,1] and [0,∞)

Dette, Holger; Studden, William J. - 2001

In this note a matrix version of the q-d algorithm is introduced. It is shown that the algorithm may be used to obtain the coeÆcients of the recurrence relations for matrix orthogonal polynomials on the interval [0,∞) and [0;1] from its moment generating functional. The algorithm is...

Rank test based on matrix perturbation theory

Ratsimalahelo, Zaka - 2001

In this paper, we propose methods of the determination of the rank of matrix. We consider a rank test for an unobserved matrix for which an estimate exists having normal asymptotic distribution of order N1/2 where N is the sample size. The test statistic is based on the smallest estimated...

Well-posedness of KdV with higher dispersion

Gorsky, Jennifer; Alexandrou Himonas, A. - In: Mathematics and Computers in Simulation (MATCOM) 80 (2009) 1, pp. 173-183

It is shown that if the dispersion of the KdV equation is replaced by a higher order dispersion ∂xm, where m≥3 is an odd integer, then the critical Sobolev exponent for local well-posedness on the circle does not change. That is, the resulting equation is locally well-posed in Hs(T), s≥−1/2.
