摘要：

In this paper we evaluate the wave function of the universe using the usual Euclidean path integral technique as proposed by Halliwell and Louko for Ashtekar's new variables. Also we consider the new regularization technique developed by Ishikawa and Ueda for evaluation of the path integral. The wave function by solving the Wheeler-DeWitt equation is also presented.
