Notes about Quasi-Mixing Operators [PDF]

Sahand Communications in Mathematical Analysis
In this article, we introduce quasi-mixing operators and construct various examples. We prove that quasi-mixing operators exist on all finite-dimensional and infinite-dimensional  Banach spaces.

BEST APPROXIMATION IN QUASI TENSOR PRODUCT SPACE AND DIRECT SUM OF LATTICE NORMED SPACES [PDF]

Journal of Algebraic Systems, 2014
We study the theory of best approximation in tensor product and the direct sum of some lattice normed spacesX_{i}. We introduce quasi tensor product space anddiscuss about the relation between tensor product space and thisnew space which we denote it by ...

Differentiation of computed sum of hourly and daily reference evapotranspiration in a semi-arid climate [PDF]

Journal of Applied Research in Water and Wastewater, 2017
Electronic weather stations have increased the availability of weather data for computing hourly and daily reference evapotranspiration (ETo). There is a rational question applied for different climate conditions whether the sum of hourly ETo computation

On The Direct Sum Of Min(Max) - CS Modules

Journal of Kufa for Mathematics and Computer, 2013
In this paper, we study the direct sum of min (max)-CS modules. We show that the direct sum of min (max)-CS modules need not be min (max)-CS module. So we give many sufficient conditions under which the direct sum of min (max)-CS modules become min (max)

On direct sums of reductive operators [PDF]

Proceedings of the American Mathematical Society, 1974
An example is given to show that the direct sum of two (distinct) reductive operators need not be reductive. The conjecture that A ⊕

Direct sums of Rickart modules

Journal of Algebra, 2012
A right \(R\)-module \(M\) with endomorphism ring \(S=\text{End}_R(M)\) is called a Rickart module if the right annihilator in \(M\) of any single element of \(S\) is a direct summand of \(M\). In general, the class of Rickart modules is not closed under direct sums, and it is interesting to study when it has this closure property.
