摘要
The possibility of evolving a partial degenerate solution from non-degenerate initial data in Ashtekar formalism is considered in a constructed example.It is found that this possibility could be realized in the time evolution given by Ashtekar's equations on a 3-dimensional manifold with topology R^(1)×S^(2).
