Synthesis of block, graft and star polymers from inorganic macroinitiators
(John Wiley & Sons, Ltd., 1998-10)
Recent advances in the synthesis of block, graft and star polymers containing inorganic macromolecular species are described. Anionic copolymerization techniques were used in the for-mation of diblock copolymers of ...
On the Oppenheimer‐Volkoff Equations in General Relativity
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-05)
We introduce a new formulation of the Oppenheimer‐Volkoff (O‐V) equations, a system of ordinary differential equations that models the interior of a star in general relativity, and we use this to give a completely rigorous ...
Extendability of Solutions of the Einstein–Yang/Mills Equations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-06)
We prove that any solution to the spherically symmetric SU (2) Einstein–Yang/Millsequations that is defined in the far field and is asymptotically flat, is globally defined. This result applies in particular to the interior ...
The Enumeration of Fully Commutative Elements of Coxeter Groups
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-05)
A Coxeter group element w is fully commutative if any reduced expression for w can be obtained from any other via the interchange of commuting generators. For example, in the symmetric group of degree n, the number of fully ...
Counting points on varieties over finite fields related to a conjecture of Kontsevich
(Springer-Verlag; Springer-Verlag Singapore Pte. Ltd., 1998-12)
We describe a characteristic-free algorithm for “reducing” an algebraic variety defined by the vanishing of a set of integer polynomials. In very special cases, the algorithm can be used to decide whether the number of ...
Characteristic and Ehrhart Polynomials
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-03)
Let A be a subspace arrangement and let χ(A,t) be the characteristic polynomial of its intersection lattice L( A). We show that if the subspaces in A are taken from , where is the type B Weyl arrangement, then χ(A,t) counts ...
Integrals of polynomials associated with tableaux and the Garsia-Haiman conjecture
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-07)
The Greatest Common Quotient of Borel-Serre and the Toroidal Compactifications of Locally Symmetric Spaces
(Birkhäuser Verlag; Birkhäuser Verlag, Basel ; Springer Science+Business Media, 1998-12)
In this paper, we identify the greatest common quotient (GCQ) of the Borel-Serre compactification and the toroidal compactifications of Hermitian locally symmetric spaces with a new compactification. Using this compactification, ...
On the Betti Numbers of Chessboard Complexes
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-09)
In this paper we study the Betti numbers of a type of simplicial complex known as a chessboard complex. We obtain a formula for their Betti numbers as a sum of terms involving partitions. This formula allows us to determine ...
A Generalization of the Hausdorff-Young Theorem
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-12)
Considering mixed-norm sequence spaces lp,q, p, q ≧ 1, C. N. Kellogg proved the following theorem: if 1 < p ≦ 2 then ⊂ lp′,2 and lp,2 ⊂ , where 1/p + 1/p′ = 1. This result extends the Hausdorff-Young Theorem.
