The Lanczos algorithm can be used both for eigenvalue problems and to solve linear systems. However, when applied to non-Hermitian matrices, the classical Lanczos algorithm is susceptible toâ€¦ (More)

1. Historical origins of Lie group theory. Nowadays when Lie groups enter in a profound way into so many areas of mathematics, their historical origin is of considerable general interest. Theâ€¦ (More)

The X-ray transform on a compact symmetric space M is here inverted by means of an explicit inversion formula. The proof uses the conjugacy of the minimal closed geodesics in M and of the maximallyâ€¦ (More)

The atypical isolates of Aeromonas salmonicida are becoming increasingly important as the frequency of isolation of bacteria belonging to this group continues to rise. The primary object of thisâ€¦ (More)

The definitions of descents and excedances in the elements of the symmetric group Sd are generalized in two different directions. First, descents and excedances are defined for indexed permutations,â€¦ (More)

An aqueous two-phase equilibrium partition system was used to assay SHBG-binding capacity. Sera from groups of postmenopausal women before and during unopposed estrogen replacement therapy wereâ€¦ (More)

1. Introduction and notation. Let S be a Riemannian globally symmetric space, G the largest connected group of isometries of S in the compact open topology. We assume that S is of the noncom-pactâ€¦ (More)
