چکیده
Assuming the continuum hypothesis there is an inseparable sequence of length ω1 that contains no Lusin subsequence, while if Martin’s Axiom and ¬CH is assumed then every inseparable sequence (of length ω1) is a union of countably many Lusin subsequences.

متن کاملZinc(II) ortho-hydroxyphenylhydrazo-β-diketonate complexes and their catalytic ability towards diastereoselective nitroaldol (Henry) reaction.
The zinc(II) complexes with ortho-hydroxy substituted arylhydrazo-β-diketonates [Zn(2)(CH(3)OH)(2)(μ-L(1))(2)] (5), [Zn{(CH(3))(2)SO}(H(2)O)(L(2))] (6), [Zn(2)(H(2)O)(2)(μ-L(3))(2)] (7) and [Zn(H(2)O)(2)(L(4))]·H(2)O (8) were synthesized by reaction of a zinc(II) salt with the appropriate hydrazo-β-diketone, HO-2-C(6)H(4)-NHN=C{C(=O)CH(3)}(2) (H(2)L(1), 1), HO-2-O(2)N-4-C(6)H(3)-NHN=C{C(=O)CH(3...

متن کاملPreparation and Structural Characterization of Methylmercury(II) Complexes of 5-Aza- and 6-Azauracil Derivatives
1:1 Methylmercury(II) com plexes o f the anti-tumour agent 6-azauracil (6 A U H ;) and its deriva tives 6-azathymine (6A T H 2), l-methyl-6-azauracil (6A M U H ) and l-m ethyl-6-azathym ine (6A M T H ) have been isolated from aqueous solutions of CH3HgOH and the respective base. N3Coordination was established by X-ray structural analysis for both [(C H ,H g)6 A U H ] (1) (pH 6 —8) and [(CH 3H ...
