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

On the algebraic immunity of direct sum constructions [PDF]
, 2021 peer reviewedIn this paper, we study sufficient conditions to improve the lower bound on the algebraic immunity of a direct sum of Boolean functions. We exhibit three properties on the component functions such that satisfying one of them is sufficient ...

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.

The direct sum order in regular modules
, 2020 In this paper, we define the direct sum relation on a module and prove that this is a partial order when the module is regular. We also focus on a regular support and a strong regular support of an element in a module, which are extensions of a ...

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 ⊕

A Hyperstructural Approach to Semisimplicity
AxiomsIn this paper, we provide the basic properties of (semi)simple hypermodules. We show that if a hypermodule M is simple, then (End(M),·) is a group, where End(M) is the set of all normal endomorphisms of M. We prove that every simple hypermodule is normal
