Euclidean Black Hole Vortices

Fay Dowker, Ruth Gregory, Jennie Traschen

We argue the existence of solutions of the Euclidean Einstein equations that correspond to a vortex sitting at the horizon of a black hole. We find the asymptotic behaviours, at th…

Black Holes in Magnetic Monopoles

K. Lee, V. P. Nair, Erick J. Weinberg

We study magnetically charged classical solutions of a spontaneously broken gauge theory interacting with gravity. We show that nonsingular monopole solutions exist only if the Hig…

Perturbations of a Stringy Black Hole

E. Raiten

We extend the three dimensional stringy black hole of Horne and Horowitz to four dimensions. After a brief discussion of the global properties of the metric, we discuss the stabili…

A Classical Instability of Reissner-Nordstrom Solutions and the Fate of Magnetically Charged Black Holes

K. Lee, V. P. Nair, E. J. Weinberg

Working in the context of spontaneously broken gauge theories, we show that the magnetically charged Reissner-Nordstrom solution develops a classical instability if the horizon is…

Brst Cohomology and Physical States in 2D Supergravity Coupled to Matter

Katsumi Itoh, Nobuyoshi Ohta

We study the BRST cohomology for two-dimensional supergravity coupled to superconformal matter in the conformal gauge. The super-Liouville and superconformal matter…

Superstring in Two Dimensional Black Hole

Shin'ichi Nojiri

We construct superstring theory in two dimensional black hole background based on supersymmetric gauged Wess-Zumino-Witten model.

Solving 3+1 QCD on the Transverse Lattice Using 1+1 Conformal Field Theory

Paul A. Griffin

A new transverse lattice model of Yang-Mills theory is constructed by introducing Wess-Zumino terms into the 2-D unitary non-linear sigma model action for link fields on a 2-…
