On the constraint algebra of quantum gravity in the loop representation
Bernd Bruegmann
Although an important issue in canonical quantization, the problem of representing the constraint algebra in the loop representation of quantum gravity has received little attentio…
Comment on the chaotic singularity in some magnetic Bianchi VI cosmologies
Beverly K. Berger
Description of the magnetic Bianchi VI cosmologies of LeBlanc, Kerr, and Wainwright in the formalisms both of Belinskii, Khalatnikov, and Lifshitz, and of Misner allows qualita…
Spectrum of the Volume Operator in Quantum Gravity
R. Loll
The volume operator is an important kinematical quantity in the non-perturbative approach to four-dimensional quantum gravity in the connection formulation. We give a general algor…
Long Range Effects of Cosmic String Structure
Bruce Allen, Bernard S. Kay, Adrian C. Ottewill
We combine and further develop ideas and techniques of Allen \& Ottewill, Phys. Rev.D, {\bf 42}, 2669 (1990) and Kay \& Studer Commun. Math. Phys., {\bf 139}, 103 (1991) for calcul…
On the Relation Between the Holomorphic Prepotential and the Quantum Moduli in SUSY Gauge Theories
J. Sonnenschein, S. Theisen, S. Yankielowicz
We give a simple proof of the relation $Λ\p_artialΛ\F= {i\over2π}b_1\langle\Trϕ^2\rangle$, which is valid for supersymmetric QCD with massless quarks. We consider g…
Compact null hypersurfaces and collapsing Riemannian manifolds
Alan D. Rendall
Restrictions are obtained on the topology of a compact divergence-free null hypersurface in a four-dimensional Lorentzian manifold whose Ricci tensor is zero or satisfies some weak…
Solutions of the Einstein equations with matter
Alan D. Rendall
Recent results on solutions of the Einstein equations with matter are surveyed and a number of open questions are stated. The first group of results presented concern asymptoticall…
Averaging inhomogeneous Newtonian cosmologies
Thomas Buchert, Juergen Ehlers
Idealizing matter as a pressureless fluid and representing its motion by a peculiar--velocity field superimposed on a homogeneous and isotropic Hubble expansion, we apply (Lagrangi…
Existence of maximal hypersurfaces in some spherically symmetric spacetimes
Gregory A. Burnett, Alan D. Rendall
We prove that the maximal development of any spherically symmetric spacetime with collisionless matter (obeying the Vlasov equation) or a massless scalar field (obeying the massles…
A Swendsen-Wang update algorithm for the Symanzik improved sigma model
A. Buonanno, G. Cella
We study a generalization of Swendsen-Wang algorithm suited for Potts models with next-next-neighborhood interactions. Using the embedding technique proposed by Wolff we test it on…
A NEW NUMERICAL APPROACH TO THE OSCILLATION MODES OF RELATIVISTIC STARS
Nils Andersson, Kostas D. Kokkotas, Bernard F. Schutz
The oscillation modes of a simple polytropic stellar model are studied. Using a new numerical approach (based on integration for complex coordinates) to the problem for the stellar…
