Even-homogeneous supermanifolds on the complex projective line
E. G. Vishnyakova
The classification of even-homogeneous complex supermanifolds of dimension 1|m, m\leq 3, on CP^1 up to isomorphism is given. An explicit description of such supermanifolds in terms…
On the category of Lie n-algebroids
Giuseppe Bonavolontà, Norbert Poncin
Lie n-algebroids and Lie infinity algebroids are usually thought of exclusively in supergeometric or algebraic terms. In this work, we apply the higher derived brackets constructio…
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…
Collisions of particles in locally AdS spacetimes II Moduli of globally hyperbolic spaces
Thierry Barbot, Francesco Bonsante, Jean-Marc Schlenker
We investigate 3-dimensional globally hyperbolic AdS manifolds containing "particles", i.e., cone singularities of angles less than along a time-like graph . To each such s…
Sub-Riemannian geometry on infinite-dimensional manifolds
Erlend Grong, Irina Markina, Alexander Vasil'ev
We generalize the concept of sub-Riemannian geometry to infinite-dimensional manifolds modeled on convenient vector spaces. On a sub-Riemannian manifold , the metric is defined…
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…
