چکیده
Abstract In this paper, we consider some examples of set algebras $$ \mathcal{A} A on ℕ. If ℰ( ) is the simple functions , then ℒ ∗ α ( denotes ‖⋅‖ -closure ). Our aim to determine a complete orthonormal system for Hilbert space ∗2 in each regarded case. Here quotient modulo null-functions.

Unconditionality with Respect to Orthonormal Systems in Noncommutative L2 Spaces
Orthonormal systems in commutative L2 spaces can be used to classify Banach spaces. When the system is complete and satisfies certain norm condition the unconditionality with respect to the system characterizes Hilbert spaces. As a noncommutative analogue we introduce the notion of unconditionality of operator spaces with respect to orthonormal systems in noncommutative L2 spaces and show that ...
متن کاملOrthonormal basis functions for modelling continuous-time systems
This paper studies continuous-time system model sets that are spanned by "xed pole orthonormal bases. The nature of these bases is such as to generalise the well-known Laguerre and two-parameter Kautz bases. The contribution of the paper is to establish that the obtained model sets are complete in all of the Hardy spaces H p (P), 1(p(R, and the right half plane algebra A(P) provided that a mild...
متن کاملOrthonormal Basis Functions for Continuous-Time Systems and Lp Convergence
In this paper, model sets for continuous–time linear time invariant systems that are spanned by fixed pole orthonormal bases are investigated. These bases generalise the well known Laguerre and two–parameter Kautz cases. It is shown that the obtained model sets are norm dense in the Hardy space H1(Π) under the same condition as previously derived by the authors for the norm denseness in the (Π ...

متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
