Abstract
By studying various, known extreme of 1) SU(3) sectors, 2) SO(5) sectors and 3) SO(3) x SO(3) sectors of gauged N = 8 supergravity in four dimensions, one finds that the deformation of seven sphere S7 gives rise to nontrivial renormalization group (RG) flow in threedimensional boundary conformalfield theory from W fixed point to IR fixed point. For SU(3) sectors, thisleads to fourparameter subspace of the supergravity scalargravity actionand we identify one of the eigenvalues of A(1) tensor of the theory with asuperpotential of scalar potential that governs RG flows on this subspace. We analyze some of the structure of the superpotential and discuss firstorder BPS domainwall solutions, using some algebraic relations between superpotential and derivatives of it with respect to fields, that determine a (super)symmetric kink solution in fourdimensional N = 8 supergravity, whichgeneralizes all the previous considerations. The BPS domainwall solutionsare equivalent to vanishing of variation of spin 1/2, 3/2 fields in the supersymmetry preserving bosonic background of gauged N = 8 supergravity. ForSO(5) sectors, there exist only nontrivial nonsupersymmetric critical points that are unstable and included in SU(3) sectors. For SO(3) x SO(3) sectors, we construct the scalar potential (never been written) explicitly and study explicit construction of firstorder domainwall solutions.
