0. Introduction. Let (A, m) be a regular local ring and let Î± and Î² be points of the real spectrum of A centered at m. Î± and Î² may be viewed as total orderings on quotients of A. Associated with Î±â€¦ (More)

It is possible (as in [4] ) to define a duality operation f â€”â€¢ f * in the ring of virtual characters of an arbitrary finite group with a split (B, 7V)-pair of characteristic p. Such a group arises asâ€¦ (More)

The panstochastic analogue of Birkhoff's Theorem on doubly-stochastic matrices is proved in the case n = 5. It is shown that this analogue fails when n > 1, n = 5.

The administration of tetanus toxoid vaccine to both adults and children represents an often neglected, but medically necessary procedure for patients who receive traumatic injuries to nature'sâ€¦ (More)

A family of polynomials parameterized by the conjugacy classes of a finite Coxeter group is investigated. These polynomials, together with the character table of the group, determine the associatedâ€¦ (More)

A type of directed multigraph called aW -digraph is introduced to model the structure of certain representations of Hecke algebras, including those constructed by Lusztig and Vogan from involutionsâ€¦ (More)
