Remarks on multivalued nonexpansive mappings
(Soochow University, 1995-01)
Convergence of fixed point sets of multivalued nonexpansive mappings is studied under both the Mosco and Hausdorff senses. A characterization for *- nonexpansive multivalued mappings is given. Also a counterexample is ...

Characterization of complex filiform Lie algebras of dimension 0 according to whether they are or not derived from others
(Universidad de Zaragoza, 1993)
In this paper, we characterize those Complex Filiform Lie Algeoras of dimension 0 which are derived from other Solvable Lie ALgebras of higher dimensions. This result and the previous one given in ({0]) allow us to lind a ...

A contact version of B.-Y. Chen's inequality and its applications to slant immersions
(Kyungpook National University, 1999)
We establish a version of B.-Y. Chen’s inequality for a submanifold of a Sasakianspace-form, tangent to the structure vector field of the ambient space. We obtain some applications and we study this inequality for slant ...

Glutamine synthetase inactivation by protein-protein interaction
(National Academy of Sciences, 1999)
Glutamine synthetase (GS; EC 6.3.1.2) is the pivotal enzyme of nitrogen metabolism in prokaryotes. Control of bacterial GS activity by reversible adenylylation has provided one of the classical paradigms of signal transduction ...

Metallicity maps of the globular cluster system in the galaxy
(IOP Publishing Ltd., 1993-01-10)
The spatial metallicity distribution in the Galaxy, as depicted by the globular cluster system, is analyzed. Two metallicity maps (on the ω - |Z| plane) corresponding to the halo and disk subsamples (Zinn 1985) have been ...

Convergence in mean of weighted sums of {an,k}-compactly uniformly integrable random elements in Banach spaces
(Hindawi, 1997)
The convergence in mean of a weighted sum ka.k(Xk EXk) of random elements in a separable Banach space is studied under a new hypothesis which relates the random elements with their respective weights in the sum: the {a.. ...
