A characterization of multiplication operators on reproducing kernel Hilbert spaces [PDF]

open access: yes, 2008
In this note, we prove that an operator between reproducing kernel Hilbert spaces is a multiplication operator if and only if it leaves invariant zero sets. To be more precise, it is shown that an operator T between reproducing kernel Hilbert spaces is a

PRODUCTS OF RADIAL DERIVATIVE AND MULTIPLICATION OPERATOR BETWEEN MIXED NORM SPACES AND ZYGMUND-TYPE SPACES ON THE UNIT BALL

open access: yes, 2014
In this paper, we obtain some characterizations of the boundedness and compactness of the products of the radial derivative and multiplication operator RMu between mixed norm spaces H(p, q, φ) and Zygmund-type spaces on the unit ball.

Resolvent Positive Linear Operators Exhibit the Reduction Phenomenon [PDF]

open access: yes, 2011
The spectral bound, s(a A + b V), of a combination of a resolvent positive linear operator A and an operator of multiplication V, was shown by Kato to be convex in b \in R.

Eigenvalues of s-type operators on C ( p ) $C(p)$ equipped with a pre-quasi norm

open access: yesJournal of Inequalities and Applications, 2020
We investigate some new topological properties of the multiplication operator on C ( p ) $C(p)$ defined by Lim (Tamkang J. Math. 8(2):213–220, 1977) equipped with the pre-quasi-norm and the pre-quasi-operator ideal formed by this sequence space and s ...

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

open access: yesJournal 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

open access: yesJournal 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”

open access: yesIEEE 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 $4 \times 128$ .
