Einstein equations with cosmological constant in Super Space-Time
Abstract
We introduce a new kind of super warped product spaces , , and , where is a supermanifold of dimension , is standard superdomain with and , subject to the warp functions , , and , respectively. In each super warped product space, , , and , it is shown that Einstein equations , with cosmological term are reducible to the Einstein equations on the super space with cosmological term , where and are functions of , , and , as well as (, ). This dependence points to the origin of cosmological terms which turn out to be within the warped structure of the super space-time. By using the Generalized Robertson-Walker space-time, as a super space-time, and demanding for constancy of we can determine the warp functions and which result in finding the solutions for Einstein equations and . We have discussed the cosmological solutions, for each kind of super warped product space, in the special case of .
