    Paper   IPM / P / 6867
       School of Physics
      Title: Sign Function and Gluing of Space-Time Manifolds within the Distributional Method
      Author(s):
    1 . S. Khakshournia
    2 . R. Mansouri
      Status: Published
      Journal: Gravitation and Cosmology
      No.: 98
      Vol.: 7
      Year: 2001
      Pages: 261-268
      Supported by: IPM
      Abstract:
    The introduction of the sign function within the Darmois-Israel formalism has bee a breakthrough in the study of the gluing manifolds and their classification within general relativity. In the equivalent distributional method introduced in the last years, the corresponding sign function has never been considered and therefore the classification of matching has not been possible. We have implemented this sign function within the distributional method successfully and applied it to static and time-dependent spherically symmetric space-times.
