Prequasiideal of the type weighted binomial matrices in the Nakano sequence space of soft functions with some applications

Journal of Inequalities and Applications, 2022
Consider the space of weighted binomial matrices in the Nakano sequence space of soft functions. We have offered some geometric and topological structures of the multiplication operator acting on this space and its associated operator ideal.

Some Properties of Prequasi Normed Generalized de La Vallée Poussin’s Mean Sequence Space

Journal of Function Spaces, 2020
In this article, we study some topological properties of the multiplication operator on generalized de La Vallée Poussin’s mean sequence space equipped with the prequasi norm and the prequasi operator ideal generated by s-numbers and this sequence space.

Corrections to “Deep Learning-Based Robust Automatic Modulation Classification for Cognitive Radio Networks”

IEEE Access, 2021
In the above article [1], in Table 4, the operator * was used to represent frame sizes, which are 2 * 128 and 4 * 128. The correct operator should be a multiplication operator $\times $ for $2 \times 128$ and $4 \times 128$ .

A Novel Multi-Criteria Group Decision-Making Approach Based on Bonferroni and Heronian Mean Operators under Hesitant 2-Tuple Linguistic Environment

Mathematics, 2021
Ambiguous and uncertain facts can be handled using a hesitant 2-tuple linguistic set (H2TLS), an important expansion of the 2-tuple linguistic set. The vagueness and uncertainty of data can be grabbed by using aggregation operators.

Compact Weighted Composition Operators and Multiplication Operators between Hardy Spaces

Abstract and Applied Analysis, 2008
We estimate the essential norm of a compact weighted composition operator 𝑢𝐶𝜑 acting between different Hardy spaces of the unit ball in ℂ𝑁. Also we will discuss a compact multiplication operator between Hardy spaces.
