Abstract
In this paper, we investigated the space-time obtained by quotients of the 
space-time. Further quotient with specific 
is considered. Taking up the first-order perturbation in metric, we estimated the backreaction of the matter field on space-time geometry. We can calculate the expectation value of the stress-energy tensor by pulling it back onto the covering space. The average null energy becomes negative when the suitable boundary condition is chosen, resulting in a traversable wormhole.
