摘要
We analyse a simple model with just a term present. Differing results are obtained depending on the boundary conditions applied. HH boundary conditions give the factor exp(1/Lambda) but in agreement with Rubakov et al. is badly behaved for negative lambda. Tunneling boundary conditions suggests a large initial lambda. If only a Lorentzian region is considered all boundary conditions suggest a large value of Lambda. This differs from the result of Strominger for such models.
