CONFORMAL ACTIONS OF NILPOTENT GROUPS ON PSEUDO-RIEMANNIAN MANIFOLDS
CONFORMAL ACTIONS PSEUDO-RIEMANNIAN MANIFOLDS

We study conformal actions of connected nilpotent Lie groups
on compact pseudo-Riemannian manifolds. We prove that if a type-(p,q)
compact manifold M supports a conformal action of a connected nilpo...

Let E denote an a±ne space modelled on Minkowski (2+1)-space E
and let ¡ be a group of isometries whose linear part L(¡) is a purely hyperbolic
subgroup of SO0
(2;1). Margulis has deˉned ...

Abstract: Given a positive and unitarily invariant Lagrangian L defined in the algebra of Hermitian matrices, and a fixed interval $[a,b]\subset\mathbb R$, we study the action defined in the Lie group...
Equivalence of Group Actions on Riemann Surfaces
Equivalence of Group Riemann Surfaces
font style='font-size:12px;'>
2011/2/24
We produce for each natural number n 3 two 1–parameter fam-ilies of Riemann surfaces admitting automorphism groups with two cyclic sub-groups H1 and H2 of orden 2n, that are conjugate in the group o...
Infinitely transitive actions on real affine suspensions
Infinite transitive action real algebraic variety suspension

A group G acts infinitely transitively on a set Y if for every positive integer m, its
action is m-transitive on Y . Given a real affine algebraic variety Y of dimension greater than
or equal to 2, ...

We produce $p$-harmonic morphisms by conformal foliations and Clifford systems. First, we give a useful criterion for a foliation on an $m$-dimensional Riemannian manifold locally generated by conform...

We defined an equivalence among group actions and find sufficient conditions for actions of compact connected Lie groups on Euclidean spaces for which the topological version of the Borel-Hirzebruch f...
