Null Strings in Schwarzschild Spacetime
Mariusz P. Dabrowski, Arne. L. Larsen
The null string equations of motion and constraints in the Schwarzschild spacetime are given. The solutions are those of the null geodesics of General Relativity appended by a null…
Are Higher Order Membranes stable in Black Hole Spacetimes?
A. L. Larsen, C. O. Lousto
We continue the study of the existence and stability of static spherical membrane configurations in curved spacetimes. We first consider higher order membranes described by a Lagra…
Cosmic Strings and Black Holes
A. L. Larsen
In the first part of this talk, I consider some exact string solutions in curved spacetimes. In curved spacetimes with a Killing vector (timelike or spacelike), the string equation…
Runaway Collapse of Witten Vortex Loops
Arne L. Larsen, Minos Axenides
We consider general properties of charged circular cosmic strings in a general family of world-sheet string models. We then specialize to a model recently proposed by Carter and Pe…
Supermembranes and Superstrings with Extrinsic Curvature
F. Aldabe, A. L. Larsen
In a recent paper Townsend suggested to associate to the D=11 solitonic membrane of N=1 supergravity a certain thickness, and then to identify this membrane with the fundamental su…
Stationary Strings and Principal Killing Triads in 2+1 Gravity
V. Frolov, S. Hendy, A. L. Larsen
A new tool for the investigation of 2+1 dimensional gravity is proposed. It is shown that in a stationary 2+1 dimensional spacetime, the eigenvectors of the covariant derivative of…
