Centers on center manifolds in the Lu system
(Elsevier B.V., 2011-09-19)
We confirm a conjecture of Mello and Coelho [Phys. Lett. A 373 (2009) 1116] concerning the existence of centers on local center manifolds at equilibria of the Lu system of differential equations on R(3). Our proof shows ...

Centers on center manifolds in the Lu system
(Elsevier B.V., 2014)
An unusual two-dimensional hydrogen-bonding network in bis(2,9-dimethyl-1,10-phenanthrolin-1-ium) peroxodisulfate dihydrates
(BLACKWELL PUBLISHING, 2008-09)
The title compound, 2C(14)H(13)N(2)(+)center dot S2O82-center dot 2H(2)O, is a protonated amine salt which is formed from two rather uncommon ionic species, namely a peroxodisulfate (pds(2-)) anion, which lies across a ...
On the number of critical periods for planar polynomial systems
(Pergamon-Elsevier B.V. Ltd, 2008-10-01)
In this paper we get some lower bounds for the number of critical periods of families of centers which are perturbations of the linear one. We give a method which lets us prove that there are planar polynomial centers of ...

Self-assembly of cyclometallated Pd(II) compounds directed by C-H center dot center dot center dot pi interactions: A structural evidence for metalloaromaticity in a cyclopalladated ring
(Elsevier B.V., 2011-01-01)
Structural studies on the two binuclear cyclometallated compounds [Pd(C-2,N-bzan)(mu-N-3)](2) (1) and [Pd(C-2,N-bzan)(mu-Pz)](2) (2) (bzan = N-benzylideneaniline) have been carried out in this work. In both compounds, C-H ...
(2S,R-S)-6-Phenyl-1-(p-tolylsulfinyl)-hexa-3(E),5(E)-dien-2-ol
(BLACKWELL PUBLISHING, 2006-10)
The molecule of the title compound, C19H20O2S, corresponds to a chiral sulfinyldienol with two stereogenic centres, viz. the C atom susbtituted by the hydroxy group and the sulfinyl S atom. The molecule displays a V-shape ...
