摘要：

This paper investigates the effects of the spatial variation of the cosmological constant LAMBDA on the spacetime geometry within and outside a massive object. It is seen that the variation of LAMBDA with the radial coordinate introduces non-trivial changes leading to spacetime closing on itself around a massive object. It may also be possible to generate interior solutions that lead to flat rotation curves of galaxies.
