摘要: Abstract We study the behavior of anisotropies in Bianchi IX universe with one extra dimension under Hartle-Hawking boundary condition. The evolution metric components imaginary time is presented paying special attention to difference from those case without dimension. confirmed be generally more rapid when present and this makes region mini-superspace where wave function has significant value a little larger. difference, however, brought about by internal space small. find that non-trivial for certain non-zero even they are relatively large. This implies primordial was anisotropic rather than isotropic.
