0 −→ c −→ g1 φ1 −→g −→ 0 such that c ⊆ Z(g1), the center of g̃. A morphism of central extensions is a Lie algebra homomorphism ψ : g1 → g2 such that φ2ψ = φ1. A universal central extension is a central extension g̃ such that there is a unique morphism from g̃ to every other central extension of g. The Schur multiplier is the kernel of the universal central extension of g. It classifies the project...

Introduction. Let A be a commutative semi-simple Banach algebra and let A(.4) be the set of nonzero multiplicative functionals on A. Denote by A' the strongly closed span of A(^4) and by A" the Banach space adjoint of A'. Modifying a construction of R. Arens [l] we introduce a multiplication in A" under which A" becomes a commutative Banach algebra. A is algebraically isomorphic to a subalgebra...

almost multiplier is rather a new concept in the theory of almost functions. in thispaper we discuss on the boundedness of almost multipliers on some special banach algebras,namely stable algebras. we also de ne an adjoint and extension for almost multiplier.

The finite field modular multiplier is the most critical component in the elliptic curve crypto processor (ECCP) consuming the maximum chip area and contributing the most to the device latency. Modular multiplication, point multiplication, point doubling are few of the critical activities to be carried out by multiplier in ECC algorithm, and should be managed without compromising on security an...

The main objective of the proposed work is implementing the 32 bit Vedic and Baugh-Wooley multiplication operation with Carry-Save methodology to reduce the average time and delay of operations. This system contain a high speed low power digital multiplier by using advantage of Vedic multiplication algorithms with a very efficient leakage control technique called multiple channel conventional m...

In this paper, a single precision IEEE 754 floatingpoint multiplier with high speed and low power is presented. The bottleneck of any single precision floating-point multiplier design is the 24x24 bit integer multiplier. Urdhava Triyakbhyam algorithm of ancient Indian Vedic Mathematics is utilized to improve its efficiency. In the proposed architecture, the 24x24 bit multiplication operation is...

Palindromic representation is generally used to reduce space and time complexities in Gaussian normal basis (GNB) multiplier with even type t. However, palindromic representation is inapplicable for a GNB multiplier with odd type t (t ≥ 2). This study therefore develops a palindromic-like representation for a GNB multiplier with odd type t. The proposed systolic GNB multiplier with odd type t r...

Scheming multipliers that are of high-speed, low power, and standard in design are of substantial research interest. By reducing the generated partial products speed of the multiplier can be increased. Several attempts have been made to decrease the number of partial products generated in a multiplication process. One of the attempt is Wallace tree multiplier. This paper aims at designing and i...

Multiple Valued Logic (MVL) has some important benefits such as increased data density, increased computational ability, reduced dynamic power dissipation Therefore with the help of Multiple Valued Logic (MVL) we have designed two quaternary multiplier architecture. The partial products in the multiplier are designed with quaternary voltage mode circuits. Each multiplier architecture is designe...
