We give bounds on finite volume expectations for a set of boundary conditions containing the support of any tempered Gibbs state and prove a theorem connecting the behavior of Gibbs states to the differentiability of the pressure for continuum statistical mechanical systems with long range superstable potentials. Convergence of grandcanonical Gibbs states is also studied. This is an extended ve...

Let IH be the n-dimensional hyperbolic space and let P be a simple polytope in IH. P is called an ideal polytope if all vertices of P belong to the boundary of IH. P is called a Coxeter polytope if all dihedral angles of P are submultiples of π. There is no complete classification of hyperbolic Coxeter polytopes. In [6] Vinberg proved that there are no compact hyperbolic Coxeter polytopes in IH...

The census provides a basic collection of noncompact hyperbolic 3-manifolds of finite volume. It contains descriptions of all hyperbolic 3manifolds obtained by gluing the faces of at most seven ideal tetrahedra. Additionally, various geometric and topological invariants are calculated for these manifolds. The findings are summarized and a listing of all manifolds appears in the microfiche suppl...

Certainly the case of manifolds is the most interesting and most complicated. The main aim of this paper is to show that Conjecture I is not absolutely groundless. First our results deal with reflection orbifolds. In this case we will prove Conjecture 1 and find that R(Tq(M), 4) is a smooth manifold of dimension ( f -4 ) , where f is the number of "faces" of the reflection orbifold (Theorem 1)....

We compute the space of L 2 harmonic forms (outside the middle degrees) on negatively curved Kähler manifolds of finite volume.

A stable hybrid method for hyperbolic problems that combines the unstructured finite volume method with high-order finite difference methods has been developed. The coupling procedure is based on energy estimates and stability can be guaranteed. Numerical calculations verify that the hybrid method is efficient and accurate.

This invited paper presents efficient solutions of the Euler and Navier-Stokes equations based on finite difference and finite volume formulations. They were obtained with several methods recently developed for the efficient analysis of steady and unsteady external flows. (i) A biased-flux method based on an explicit finite volume formulation is first presented for the solution of the Euler equ...
