Recently, Takahashi has introduced the James and von Neumann-Jordan type constants. In this paper, we present some sufficient conditions for uniform normal structure and therefore the fixed point property of a Banach space in terms of the James and von Neumann-Jordan type constants and the Ptolemy constant. Our main results of the paper significantly generalize and improve many known results in...

In this paper we characterize the left Jordan derivations on Banach algebras. Also, it is shown that every bounded linear map $d:mathcal Ato mathcal M$ from a von Neumann algebra $mathcal A$ into a Banach $mathcal A-$module $mathcal M$ with property that $d(p^2)=2pd(p)$ for every projection $p$ in $mathcal A$ is a left Jordan derivation.

Mathieu and Ruddy proved that if be a unital spectral isometry from a unital C*-algebra Aonto a unital type I C*-algebra B whose primitive ideal space is Hausdorff and totallydisconnected, then is Jordan isomorphism. The aim of this note is to show that if be asurjective spectrum preserving additive map, then is a Jordan isomorphism without the extraassumption totally disconnected.

A century ago, Camille Jordan proved that the complex general linear group GLn(C) has the Jordan property: there is a Jordan constant Cn such that every finite subgroup H ≤ GLn(C) has an abelian subgroup H1 of index [H : H1] ≤ Cn. We show that every connected algebraic group G (which is not necessarily linear) has the Jordan property with the Jordan constant depending only on dimG, and that the...

Let A be a unital algebra and M be a unital A-bimodule. A characterization of generalized derivations and generalized Jordan derivations from A into M, through zero products or zero Jordan products, is given. Suppose that M is a unital left A-module. It is investigated when a linear mapping from A into M is a Jordan left derivation under certain conditions. It is also studied whether an algebra...

| We present a new low-complexity bit-parallel canonical basis multiplier for the eld GF2 m generated by a n all-one-polynomial. The proposed canon-ical basis multiplier requires m 2 , 1 XOR gates and m 2 AND gates. We also extend this canonical basis multiplier to obtain a new bit-parallel normal basis multiplier.

The accuracy of the multiplication depends on the precision of the multiplier. The variable precision floating point multiplier will have more accuracy when compared with the fixed precision multiplier. In this paper a variable precision floating point multiplier is considered. An effective BIST test pattern generator for variable precision floating point multiplier is proposed. A BIST TPG cons...

The present paper is an attempt to: 1- Demonstrate how money is created (by the nature of the system), and to estimate the inflation resulting from monetary factors in both usurious and non-usurious systems. Operational aspects of Islamic and non-Islamic banking systems are compared. 2- Introduce a corrective term to be added to the multiplier of the supply of money, in order to prevent the und...
