Gregory, R. & Harvey, J. A. (2003). Spacetime decay of cones at strong coupling. Classical and Quantum Gravity 20(19): L231-L237.

Author(s) from Durham


We study time-dependent solutions in dilaton gravity which correspond to the decay of conical spacetimes. In string theory this can be interpreted as a strong coupling limit of the decay of a non-supersymmetric orbifold spacetime with localized tachyons.
