CONFORMAL ACTIONS OF NILPOTENT GROUPS ON PSEUDO-RIEMANNIAN MANIFOLDS
CONFORMAL ACTIONS PSEUDO-RIEMANNIAN MANIFOLDS
2015/10/14
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 ...
Optimal paths for symmetric actions in the unitary group

2011/9/5
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...
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
2011/1/19
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, ...
On the Construction of $p$-harmonic Morphisms and Conformal Actions
$p$-harmonic morphism Clifford system homogeneous function conformal field
2007/12/11
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...

On the Validity of the Borel-Hirzebruch Formula for Topological Actions
Lie group actions characteristic classes cohomology classifiying spaces weights
2010/3/4
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...
