In this paper we prove that compact conformally flat cohomogeneity one hypersurfaces of "I?"+'.

In this paper, we look for metrics of cohomogeneity one in D = 8 and D = 7 dimensions with Spin(7) and G 2 holonomy, respectively. In D = 8, we first consider the case of principal orbits that are S 7 , viewed as an S 3 bundle over S 4 with triaxial squashing of the S 3 fibres. This gives a more gen
Let M be a smooth manifold endowed with a flat conformal structure and F Ξ» (M) the space of densities of degree Ξ» on M. We study the space D 3 Ξ»,Β΅ (M) of third-order differential operators from F Ξ» (M) to F Β΅ (M) as a module over the conformal Lie algebra o(p + 1, q + 1). We prove that D 3 Ξ»,Β΅ (M) i
