Recurrence and mixing recurrence of multiplication operators [PDF]

Mathematica Bohemica
Let $X$ be a Banach space, $\mathcal{B}(X)$ the algebra of bounded linear operators on $X$ and $(J, \|{\cdot}\|_J)$ an admissible Banach ideal of $\mathcal{B}(X)$.

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.

On multiplicative mappings of rings of operators [PDF]

Proceedings of the American Mathematical Society, 1962
Let L(hn) be the aggregate of linear transformations (sometimes called operators) of the complex n dimensional Hilbert space hn into itself. All members of L(hn) are bounded and we assign to L(hn) the topology induced by the usual metric. The determinant is a well defined mapping of L(hn) into the complex numbers (see [1]) which is continuous ...

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.

Norms of some operators between weighted-type spaces and weighted Lebesgue spaces

AIMS Mathematics, 2023
We calculate the norms of several concrete operators, mostly of some integral-type ones between weighted-type spaces of continuous functions on several domains.

Operational Momentum in Multiplication and Division?

PLoS ONE, 2014
Biases are commonly seen in numerical cognition. The operational momentum (OM) effect shows that responses to addition and subtraction problems are biased in the whole-number direction of the operation. It is not known if this bias exists for other arithmetic operations.

Hybrid Quantum Protocols for Secure Multiparty Summation and Multiplication

Scientific Reports, 2020
The summation and multiplication are two basic operations for secure multiparty quantum computation. The existing secure multiparty quantum summation and multiplication protocols have (n, n) threshold approach and their computation type is bit-by-bit ...
