The M-theory lift of N = 1 G 2 -invariant RG flow via a combinatoric use of the 4dimensional RG flow and 11-dimensional Einstein-Maxwell equations was found some time ago. The 11-dimensional metric, a warped product of an asymptotically AdS 4 space with a squashed and stretched 7-sphere, for SU(3)-invariance was found before. In this paper, by choosing the 4-dimensional internal space as CP 2 space, we discover an exact solution of N = 1 G 2 -invariant flow to the 11-dimensional field equations. By an appropriate coordinate transformation on the three internal coordinates, we also find an 11-dimensional solution of N = 1 G 2 -invariant flow interpolating from N = 8 SO(8)-invariant UV fixed point to N = 1 G 2 -invariant IR fixed point. In particular, the 11-dimensional metric and 4-forms at the N = 1 G 2 fixed point for the second solution will provide some hints for the 11-dimensional lift of whole N = 1 SU(3) RG flow connecting this N = 1 G 2 fixed point to N = 2 SU(3) × U(1) R fixed point in 4-dimensions. the RG flows [5], we focus on the G 2 -invariant sector (which is a subset of above SU(3)invariant sector) in 4-dimensional viewpoint by constraining the four arbitrary supergravity fields together with the particular condition. There exist a supersymmetric N = 1 G 2 critical point and two nonsupersymmetric SO(7) ± critical points [29,30] in this sector. If we take the different constraints on the supergravity fields, then we are led to the SU(3) × U(1) Rinvariant sector where there are a supersymmetric N = 2 SU(3) × U(1) R critical point and a nonsupersymmetric SU(4) − critical point [31].The 11-dimensional metric is found by [26] where the compact 7-dimensional metric and warp factor are completely determined in local frames. The two geometric parameters, by constraints, that are nothing but the above supergravity fields, depend on the AdS 4 radial 2 coordinate and are subject to the RG flow equations [7,5] in 4-dimensional gauged supergravity. The global coordinates for S 7 appropriate for the base six-sphere S 6 ≃ G 2 SU (3) preserve the Fubini-Study metric on CP 2 and this describes the ellipsoidally deformed S 7 [25]. On the other hand, by using the relation to the Hopf fibration on CP 3 ≃ SU (4) SU (3)×U (1) explicitly and keeping only the CP 2 space, one can change the remaining three local frames in 7-dimensional manifold via an orthogonal transformation [26]. Each global coordinates depends on each base six-spheres they use.What is the 11-dimensional lift of holographic N = 1 supersymmetric SU (3)-invariant RG flow [13] connecting from N = 1 G 2 critical point to N = 2 SU(3) × U(1) R critical point? At each critical point, the 4-forms are known in different background. Along the supersymmetric RG flow, one expects that there exist the extra 4-forms which should vanish at the critical points. In order to describe the whole RG flow, one needs to have the consistent background.Around N = 2 SU(3) × U(1) R IR fixed point, the use of global coordinates for Hopf fibration on CP 3 was done in [8].
