Pseudostarlikeness and Pseudoconvexity of Multiple Dirichlet Series

open access: yesUniversal Journal of Mathematics and Applications, 2023
Let $p\in {\Bbb N}$, $s=(s_1,\ldots,s_p)\in {\Bbb C}^p$, $h=(h_1,\ldots,h_p)\in {\Bbb R}^p_+$, $(n)=(n_1,\ldots,n_p)\in {\Bbb N}^p$ and the sequences $\lambda_{(n)}=(\lambda^{(1)}_{n_1},\ldots,\lambda^{(p)}_{n_p})$ are such that $0<\lambda^{(j)}_1 ...

STABILITY-PRESERVING PERTURBATION OF THE MAXIMAL TERMS OF DIRICHLET SERIES

open access: yesПроблемы анализа, 2022
We study stability of the maximal term of the Dirichlet series with positive exponents, the sum of which is an entire function. This problem is of interest, because the Leont’ev formulas for coefficients calculated using a biorthogonal system of ...

Differential Subordination and Superordination of Multivalent Functions Involving Differential Operator

open access: yesAl-Mustansiriyah Journal of Science, 2021
In the present work, we derive some properties of subordination and superordination results associated with the Hadamard product concept involving the composition of the differential operator.

Hermite-Hadamard Type Inequalities for Composite Log-Convex Functions [PDF]

open access: yesMathematics and Statistics, 2020
© 2020 by authors, all rights reserved. Hermite-Hadamard type inequalities related to convex functions are widely being studied in functional analysis. Researchers have refined the convex functions as quasi-convex, h-convex, log-convex, m-convex, (α,m)-convex and many more.

Smooth and Strong PCPs [PDF]

open access: yes, 2020
Probabilistically checkable proofs (PCPs) can be verified based only on a constant amount of random queries, such that any correct claim has a proof that is always accepted, and incorrect claims are rejected with high probability (regardless of the given

Pseudostarlike and pseudoconvex Dirichlet series of the order $\alpha$ and the type $\beta$

open access: yesМатематичні Студії, 2020
The concepts of the pseudostarlikeness of order $\alpha\in [0,\,1)$ and type $\beta\in (0,\,1]$ and the pseudoconvexity of order $\alpha$ and type $\beta$ are introduced for Dirichlet series with null abscissa of absolute convergence.

On certain subclass of Dirichlet series absolutely convergent in half-plane

open access: yesМатематичні Студії, 2022
Denote by $\mathfrak{D}_0$ a class of absolutely convergent in half-plane $\Pi_0=\{s\colon \text{Re}\,s 0$, $h0$. For $0\le\alpha\alpha$ for all $s\in \Pi_0$.

Some Interesting Inequalities for the Class of Generalized Convex Functions of Higher Order

open access: yesJournal of Function Spaces, 2023
In this paper, we study a generalized version of strongly reciprocally convex functions of higher order. Firstly, we prove some basic properties for addition, scalar multiplication, and composition of functions.

A ZX-Calculus with Triangles for Toffoli-Hadamard, Clifford+T, and Beyond [PDF]

open access: yes, 2018
We consider a ZX-calculus augmented with triangle nodes which is well-suited to reason on the so-called Toffoli-Hadamard fragment of quantum mechanics. We precisely show the form of the matrices it represents, and we provide an axiomatisation which makes

Mathematical evaluation on the applicability of bolter miners based on variable weight fuzzy theory

open access: yesMeitan xuebao, 2023
With remote automatic control and ground control, bolter miners have the significant technical advantages of digging-bolting-drilling, full width cutting, driving-bolting synchronization, bolting-transporting parallel, multi-anchor balance and so on, and
