On the Product of Semi-groups of Operators1

A tensor product approach to the abstract partial fourier transforms over semi-direct product groups

In this article, by using a partial on locally compact semi-direct product groups, we present a compatible extension of the Fourier transform. As a consequence, we extend the fundamental theorems of Abelian Fourier transform to non-Abelian case.

Abstract structure of partial function $*$-algebras over semi-direct product of locally compact groups

This article presents a unified approach to the abstract notions of partial convolution and involution in $L^p$-function spaces over semi-direct product of locally compact groups. Let $H$ and $K$ be locally compact groups and $tau:Hto Aut(K)$ be a continuous homomorphism.  Let $G_tau=Hltimes_tau K$ be the semi-direct product of $H$ and $K$ with respect to $tau$. We define left and right $tau$-c...

On the Structure of Some Deficiency Zero Groups

$C^{*}$-semi-inner product spaces

In this paper, we introduce a generalization of Hilbert $C^*$-modules which are pre-Finsler modules, namely, $C^{*}$-semi-inner product spaces. Some properties and results of such spaces are investigated, specially the orthogonality in these spaces will be considered. We then study bounded linear operators on $C^{*}$-semi-inner product spaces.

A Comparative Study of Strategy Instrument through Process vs. Product Writing on IELTS Writing Performance of Iranian EFL Learners

The present study attempted to investigate the writing performance of EFL learners through process vs. product writing on IELTS test. To do this, the researcher randomly selected 60 candidates who wanted to take the IELTS Test. They had already taken and passed several technical courses regarding the skills in that test. After they were divided into two experimental groups, they were given a wr...
