Summary Several iterative methods for maximal correlation problems (MCPs) have been proposed in the literature. This paper deals with the convergence of these iterations and contains three contributions. Firstly, a unified and concise proof of the mo

The Maxbet problem is one important generalization of the well-known canonical correlation analysis (CCA). For the general case, solving Maxbet globally is a very challenging problem. In searching the global solution of Maxbet, in this paper, we firs

The Meany inequality gives an upper bound in the Euclidean norm for a product of rank-one projection matrices. In this paper we further derive a lower bound related to this inequality. We discuss the internal relationship between the upper bounds giv

In this note, the continuity results of weak vector solutions and global vector solutions to a parametric generalized Ky Fan inequality are established by using a new scalarization method. Our results improve the corresponding ones of Li and Fang (J.

SUMMARY We study the linearization method to estimate the backward error of approximate solutions to several least squares problems, including the scaled total least squares (STLS) problem, the equality constrained least squares (LSE) problem, and th

The quasi-classical trajectory calculations O++DH(v = 0, j = 0)→OD++H reactions on the RODRIGO potential energy surface have been carried out to study the isotope effect on stereo-dynamics at the collision energies of 1.0, 1.5, 2.0, and 2.5 eV. The

Recently, Psarrakos obtained a lower bound, which depends on a real parameter ν, for the distance between the pseudospectrum of a matrix polynomial and a given point that lies out of it. In this note, we study the best choice of the parameter. As a
