On the pointwise behavior of semi-classical measures
(Springer-Verlag, 1996-01)
In this paper we concern ourselves with the small ħ asymptotics of the inner products of the eigenfunctions of a Schrödinger-type operator with a coherent state. More precisely, let ψ j ħ and E j ħ denote the eigenfunctions ...
Some hidden relations involving the ten symmetry classes of plane partitions
(Elsevier, 1994-11)
Let B be a partially ordered product of three finite chains. For any group G of automorphisms of B, let NG(B, q) denote the rank generating function for G-invariant order ideals of B. If we regard B as a rectangular prism, ...
An investigation of the limiting behavior of particle-like solutions to the Einstein-Yang/Mills equations and a new black hole solution
(Springer-Verlag, 1994-03)
A mathematical investigation of the limiting behavior of particle-like solutions of Einstein-Yang-Mills equations leads to a discovery of a new type of black hole solution.
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 ...
Legendrian distributions with applications to relative Poincaré series
(Springer-Verlag, 1995-12)
Hausdorff Dimension and Limits of Kleinian Groups
(Birkhäuser Verlag; Birkhäuser Verlag, Basel ; Springer Science+Business Media, 1999-06)
In this paper we prove that if M is a compact, hyperbolizable 3-manifold, which is not a handlebody, then the Hausdorff dimension of the limit set is continuous in the strong topology on the space of marked hyperbolic ...
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 ...
On the Fully Commutative Elements of Coxeter Groups
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1996-10)
Let W be a Coxeter group. We define an element w ∈ W to be fully commutative if any reduced expression for w can be obtained from any other by means of braid relations that only involve commuting generators. We give several ...
On a problem of H. N. Gupta
(Kluwer Academic Publishers; Springer Science+Business Media, 1996-07)
It is shown that the axiom ‘For any points x, y, z such that y is between x and z , there is a right triangle having x and z as endpoints of the hypotenuse and y as foot of the altitude to the hypotenuse’, when added to ...
Eulerian numbers, tableaux, and the Betti numbers of a toric variety
(Elsevier, 1992-04-02)
Let [Sigma] denote the Coxeter complex of Sn, and let X([Sigma]) denote the associated toric variety. Since the Betti numbers of the cohomology of X([Sigma]) are Eulerian numbers, the additional presence of an Sn-module ...
