let us obtain the Wheeler-DeWitt equation corresponding to the above potential. We pass over a M-independent description with the following substitution in the Hamilton-Jacobi equation (9). $$S\rightarrow M~S,~~ \phi\rightarrow M{\phi}^{\frac {1}{2}},
~~V(\phi)\rightarrow M~V(\phi).$$ The Wheeler-DeWitt equation that follows from (8) or (9) is $$\left[{{\partial^2}\over {\partial a^2}}-{1\over a^2}{{\partial^2}\over
{\partial \phi^2}}-a^2(1-a^22V(\phi))\right]\Psi=0.$$ As is evident from the classical equation (28) or the Wheeler-DeWitt equation (55), we find the two turning points at $a_0=0$ and at $a_{\sc{T}}={1\over {\sqrt{2V}}}$. It should be pointed out that we have confined the discussions to regions in which the potential $V(\phi)$ can be approximated by a constant $V_0$, acting like a cosmological constant, so that the $\phi$ dependence in (55) can be effectively ignored. We now write (53) as $$\Psi=N_0\,e^{-iS_{eff}}$$ where $$S_{eff}={{(a^22V-1)^{3/2}}\over {3\times 2V}}.$$ According to ‘wormhole dominance’ proposal, $N_0$ is given by $$N_o = {{\exp \left[{-iS_{eff} (a_{\sc{T}},0)}\right]} \over 
{1 - \exp {\left[- 2i S_{eff} (a_{\sc{T}},0) \right]}} }\,,$$ where $$S_{eff} (a_{\sc{T}}, 0) = S_{eff}{\vert_{0}^{a_{\sc{T}}}}\,.$$ Evaluating (59) we find $$N_o = {{\exp ({1\over {3\times 2V}})} \over 
{(1 - e^{2\over {3\times 2V}})}}\,$$ taking $(-1)^{3/2}=-i$. Continuing in the region $2a^2V\,<\,1$, we get $$\Psi=C_1e^{{1\over {3\times 2V}}\left[1-(1-a^22V)^{3\over 2}\right]}\,,$$ where $$C_1={1\over {1-\exp({2\over {3\times 2V}})}}\,.$$ Equation (61) is the wavefunction of wormhole-dominance proposal.
