A new distributional approach to signature change
The authors have studied the singular hypersurfaces in general relativity by using Colombeau's generalized functions [\textit{J. F. Colombeau}, Multiplication of Distributions, Lect. Notes Math. 1532, Springer, Berlin (1992; Zbl 0815.35002)] by adopting the distributional approach [\textit{M. Khorrami} and \textit{R. Mansouri}, J. Math. Phys. 35, 951-958 (1994; Zbl 0803.53052); 37, 5672-5683 (1996; Zbl 0864.53060)].
