On certain arithmetical functions of exponents in the factorization of integers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Some new results for the maximum and minimum exponents in factorizing integers are obtained. Related functions and generalized arithmetical functions are also introduced.

On epimorphisms and structurally regular semigroups [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2021
In this paper we study epimorphisms, dominions and related properties for some classes of structurally (n,m)-regular semigroups for any pair (n,m) of positive integers. In Section 2, after a brief introduction of these semigroups, we prove that the class

The Frobenius number associated with the number of representations for sequences of repunits

open access: yesComptes Rendus. Mathématique, 2023
The generalized Frobenius number is the largest integer represented in at most $p$ ways by a linear combination of nonnegative integers of given positive integers $a_1,a_2,\,\dots ,\,a_k$. When $p=0$, it reduces to the classical Frobenius number. In this

Generalized Concatenated Codes over Gaussian and Eisenstein Integers for Code-Based Cryptography

open access: yesCryptography, 2021
The code-based McEliece and Niederreiter cryptosystems are promising candidates for post-quantum public-key encryption. Recently, q-ary concatenated codes over Gaussian integers were proposed for the McEliece cryptosystem, together with the one-Mannheim ...

Generalized Universal Coding of Integers

open access: yesCoRR, 2022
Universal coding of integers~(UCI) is a class of variable-length code, such that the ratio of the expected codeword length to $\max\{1,H(P)\}$ is within a constant factor, where $H(P)$ is the Shannon entropy of the decreasing probability distribution $P$.

On generalized degenerate Euler–Genocchi polynomials

open access: yesApplied Mathematics in Science and Engineering, 2023
We introduce the generalized degenerate Euler–Genocchi polynomials as a degenerate version of the Euler–Genocchi polynomials. In addition, we introduce their higher-order version, namely the generalized degenerate Euler–Genocchi polynomials of order α ...

HS-integral and Eisenstein integral mixed circulant graphs

open access: yesTheory and Applications of Graphs, 2023
A mixed graph is called \emph{second kind hermitian integral} (\emph{HS-integral}) if the eigenvalues of its Hermitian-adjacency matrix of the second kind are integers.

The Hermitian -Conjugate Generalized Procrustes Problem

open access: yesAbstract and Applied Analysis, 2013
We consider the Hermitian -conjugate generalized Procrustes problem to find Hermitian -conjugate matrix such that is minimum, where , , , and (, ) are given complex matrices, and and are positive integers. The expression of the solution to Hermitian
