Yg. Ma et Cb. Liang, DEGENERATE SOLUTION EVOLVED FROM NONDEGENERATE INITIAL DATA IN ASHTEKARS FORMALISM, Chinese Physics Letters, 15(7), 1998, pp. 475-476
The possibility of evolving a partial degenerate solution from non-deg
enerate initial data in Ashtekar formalism is considered in a construc
ted example. It is found that this possibility could be realized in th
e time evolution given by Ashtekar's equations on a 3-dimensional mani
fold with topology R-1 x S-2 .
