Fuzzy near best approximation as a generalization of fuzzy best approximation [PDF]

Journal of Mahani Mathematical Research
‎‎‎Given a fuzzy normed space, we will introduce the notion of fuzzy near best approximation as a generalization of the notion of fuzzy best approximation.

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 ...

Proximinality in generalized direct sums [PDF]

International Journal of Mathematics and Mathematical Sciences, 2004
We consider proximinality and transitivity of proximinality for subspaces of finite codimension in generalized direct sums of Banach spaces. We give several examples of Banach spaces where proximinality is transitive among subspaces of finite codimension.

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

Spectrum of the Direct Sum of Operators

Electronic Journal of Differential Equations, 2011
In this work, a connection between some spectral properties of direct sum of operators in the direct sum of Hilbert spaces and its coordinate operators has been investigated.

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 sum of Intuitionistic fuzzy quasi injective s-act

Academic Science Journal
In order to define the intuitionistic fuzzy s-act of the direct sum Ai ⨁ Aj, we first introduce the idea of the direct sum of intuitionistic fuzzy s-act (L = Li ⨁ Lj) of A and go over a few associated properties if Li and Lj are intuitionistic fuzzy s ...
