How to Create a 2-D Black Hole
V. Frolov, S. Hendy, A. L. Larsen
The interaction of a cosmic string with a four-dimensional stationary black hole is considered. If a part of an infinitely long string passes close to a black hole it can be captur…
How to Create a 2-D Black Hole

The interaction of a cosmic string with a four-dimensional stationary black hole is considered. If a part of an infinitely long string passes close to a black hole it can be captur…
Quantum Tunneling Effect in Oscillating Friedmann Cosmology
M. P. Dabrowski, A. L. Larsen
It is shown that the tunneling effect in quantum cosmology is possible not only at the very beginning or the very end of the evolution, but also at the moment of maximum expansion…
Circular Strings and Multi-Strings in de Sitter and Anti de Sitter Spacetimes
H. J. de Vega, A. L. Larsen, N. Sánchez
The exact general solution of circular strings in dimensional de Sitter spacetime is described completely in terms of elliptic functions. The novel feature here is that one s…
Strings and Multi-Strings in Black Hole and Cosmological Spacetimes
A. L. Larsen, N. Sánchez
Recent results on classical and quantum strings in a variety of black hole and cosmological spacetimes, in various dimensions, are presented. The curved backgrounds under considera…
STATIONARY STRINGS AND 2-D BLACK HOLES
V. P. Frolov, A. L. Larsen
A general description of string excitations in stationary spacetimes is developed. If a stationary string passes through the ergosphere of a 4-dimensional black hole, its world-she…
