A dynamical systems approach to geodesics in Bianchi cosmologies
Ulf S Nilsson, C. Uggla, J. Wainwright
To understand the observational properties of cosmological models, in particular, the temperature of the cosmic microwave background radiation, it is necessary to study their null…
Matter Coupled AdS_3 Supergravities and Their Black Strings
N. S. Deger, A. Kaya, E. Sezgin +1
We couple n copies of N=(2,0) scalar multiplets to a gauged N=(2,0) supergravity in 2+1 dimensions which admits AdS_3 as a vacuum. The scalar fields are charged under the gauged R-…
Equivalence of Chern-Simons gauge theory and WZNW model using a BRST symmetry
Jens Fjelstad, Stephen Hwang
The equivalence between the Chern-Simons gauge theory on a three-dimensional manifold with boundary and the WZNW model on the boundary is established in a simple and general way us…
An almost isotropic cosmic microwave temperature does not imply an almost isotropic universe
U. S. Nilsson, C. Uggla, J. Wainwright +1
In this letter we will show that, contrary to what is widely believed, an almost isotropic cosmic microwave background (CMB) temperature does not imply that the universe is ``close…
Two antisymmetric hypermultiplets in N=2 SU(N) gauge theory: Seiberg-Witten curve and M-theory interpretation
I. Ennes, S. Naculich, H. Rhedin +1
The one-instanton contribution to the prepotential for N=2 supersymmetric gauge theories with classical groups exhibits a universality of form. We extrapolate the observed regulari…
The state space and physical interpretation of self-similar spherically symmetric perfect-fluid models
B. J. Carr, A. A. Coley, M. Goliath +2
The purpose of this paper is to further investigate the solution space of self-similar spherically symmetric perfect-fluid models and gain deeper understanding of the physical aspe…
