Classification of maximal transitive prolongations of super-Poincaré algebras
Andrea Altomani, Andrea Santi
Let be a complex vector space with a non-degenerate symmetric bilinear form and an irreducible module over the Clifford algebra determined by this form. A s…
Associated Families of Immersions of Three Dimensional CR Manifolds in Euclidean Spaces
Andrea Altomani, Marie-Amélie Lawn
We consider isometric immersions in arbitrary codimension of three-dimensional strongly pseudoconvex pseudo-hermitian CR manifolds into the Euclidean space and gener…
Tanaka structures modeled on extended Poincaré algebras
Andrea Altomani, Andrea Santi
Let (V,(.,.)) be a pseudo-Euclidean vector space and S an irreducible Cl(V)-module. An extended translation algebra is a graded Lie algebra m = m_{-2}+m_{-1} = V+S with bracket giv…
Reductive compact homogeneous CR manifolds
Andrea Altomani, Costantino Medori, Mauro Nacinovich
We consider a class of compact homogeneous CR manifolds, that we call -reductive, which includes the orbits of minimal dimension of a compact Lie group in an alg…
Isometric and CR pluriharmonic immersions of three dimensional CR manifolds in Euclidean spaces
Andrea Altomani, Marie-Amélie Lawn
Using a bigraded differential complex depending on the CR and pseudohermitian structure, we give a characterization of three-dimensional strongly pseudoconvex pseudo-hermitian CR-m…
A characterization of CR quadrics with a symmetry property
Andrea Altomani, Costantino Medori
We study CR quadrics satisfying a symmetry property which is slightly weaker than the symmetry property , recently introduced by W. Kaup, which requires the exist…
