Groups quasi-isometric to symmetric spaces

open access: yes, 1996
We determine the structure of finitely generated groups which are quasi-isometric to symmetric spaces of noncompact type, allowing Euclidean de Rham factors If $X$ is a symmetric space of noncompact type with no Euclidean de Rham factor, and $\Ga$ is a ...

Estimation of genetic variability, expected genetic advance, correlation and path analysis in field pea (Pisum sativum L.)

open access: yesElectronic Journal of Plant Breeding, 2016
The investigation was undertaken to estimate the genetic parameters for nine characters with 12 genotypes of field pea. Based on the mean performance, the genotypes HFP 1016, IPF-13-14, Prakash and Pant P 243 showed higher performance for yield ...

Ligand “Brackets” for Ga–Ga Bond

open access: yesInorganic Chemistry, 2016
The reactivity of digallane (dpp-Bian)Ga-Ga(dpp-Bian) (1) (dpp-Bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) toward acenaphthenequinone (AcQ), sulfur dioxide, and azobenzene was investigated. The reaction of 1 with AcQ in 1:1 molar ratio proceeds via two-electron reduction of AcQ to give (dpp-Bian)Ga(μ2-AcQ)Ga(dpp-Bian) (2), in which ...

Equivariant torsion of locally symmetric spaces

open access: yes, 1996
The equivariant holomorphic torsion of a compact locally symmetric manifold and an automorphism is expressed as a special value of a zeta function built out of geometric data (closed geodesics) of the manifold.Comment: LATEX, 24 ...

The hyperbolic moduli space of flat connections and the isomorphism of symplectic multiplicity spaces

open access: yes, 1996
Let $G$ be a simple complex Lie group, $\alg{g}$ be its Lie algebra, $K$ be a maximal compact form of $G$ and $\alg{k}$ be a Lie algebra of $K$. We denote by $X\rightarrow \overline{X}$ the anti-involution of $\alg{g}$ which singles out the compact form $

Twistor spaces of non-flat Bochner-K\"ahler manifolds

open access: yes, 1996
For the twistor spaces of the Bochner-K\"ahler manifold $M = H^l \times P^n$, systems of holomorphic coordinates are constructed. As an application of them, an explicit description of the moduli space of relative deformations of fibers of $M$'s twistor ...

New examples of conservative systems on S^2 possessing an integral cubic in momenta

open access: yes, 1997
It has been proved that on 2-dimensional orientable compact manifolds of genus $g>1$ there is no integrable geodesic flow with an integral polynomial in momenta.

The singularities of Yang-Mills connections for bundles on a surface. I. The local model

open access: yes, 1994
Let $\Sigma$ be a closed surface, $G$ a compact Lie group, not necessarily connected, with Lie algebra $g$, endowed with an adjoint action invariant scalar product, let $\xi \colon P \to \Sigma$ be a principal $G$-bundle, and pick a Riemannian metric and
