Abstract

We have studied volumes of the 3-cycle and the compact 5-volumes for the β\beta transformed geometry and it comes out to be decreasing except one choice for which the torus do not stay inside the 3-cycle and ``5-cycle.'' There are 3 possible ways to construct these cycles. one is as mentioned above and the other two are, when the torus stay inside the cycle and when both the torus and the cycle shares a common direction. Also, we have argued that under β\beta deformation there arises a non-trivial ``potential'' as the SL(3,R)SL(3,R) transformation mixes up the fields. If we start with a flat space after the SL(3,R)SL(3,R) transformation the Ricci-scalar of the transformed geometry do not vanishes but the transformed solution is reminiscent of NS5-brane. We have explicitly, checked that β\beta-transformation indeed is a marginal deformation in the gravity side.
