This paper deals with the weak subdifferentials. The properties of the weak subdifferentials are examined. It is showed that the weak subdifferential of a function having a global minimum is not empty.Key Words: Subdifferential, Weak subgradient, Weak subdifferential. 

An efficient synthesis of 3-aryl-2-cyclohexylamino-6,7-dihydro-1H-indole-4(5H)-ones using ferric perchlorate as the catalyst via four-component reaction between cyclohexylisocyanide, an aldehyde, a cyclic 1,3-dicarbonyl compound and ammonium acetate in acetonitrile is described.Key Words: cyclohexylisocyanide, cyclic 1,3-dicarbonyl compound, multi-component reaction;1H-Indole-4(5H)-ones. 

Influence functions give a measure of robustness of the statistics estimated from a sample against the sample data. In this study, first, the concept of influence functions is  xamined, and then the influence functions for mean and variance are given.…

The new mild chromium (VI) oxidizing agent, quinoxalinium bromochromate (QxBC), was prepared and characterized. This new compound is effective in the oxidation of alcohols and in the bromination of aromatic compounds.  Keywords: Quinoxalinium Bromochromate, Oxidation, Alcohols, Bromination

Let A be a Banach algebra with a bounded approximate identity. Let  and be respectively, the topological centers of the algebras A** and (AA*)* with respect to the second Arens multiplication. In this paper, we show that is isometrically isomorphic…
