Permutation Orbifold of N=2 Supersymmetric Minimal Models
Permutation Orbifold N=2 Supersymmetric Minimal Models

2010/12/23
In this paper we apply the previously derived formalism of permutation orbifold conformal field theories to N=2 supersymmetric minimal models. By interchanging extensions and permutations of the fact...
Propagation of extended objects across singularity of time dependent orbifold
cosmological singularity p-brane Milne space

2010/3/18
In this paper we argue that the compactified Milne space is a promising model of the cosmological singularity. It is shown that extended objects like strings propagate in a well-defined manner across ...
