[Retracted] An Evaluation Model of Urban‐Rural Exchange Teachers in Elementary School Based on Optimal Control Neural Network

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this paper, an optimal control neural network algorithm is used to conduct an in‐depth study and analysis of the evaluation of elementary school urban‐rural exchange teachers, and an optimal control neural network evaluation model is designed and applied to the actual elementary school urban‐rural exchange process.

On new sharp theorems for multifunctional BMOA type spaces in bounded pseudoconvex domains

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2020
We provide new equivalent expressions in the unit ball and pseudoconvex domains for multifunctional analytic BMOA type space. We extend in various directions a known theorem of atomic decomposition of BMOA type spaces in the unit ball.

On the Fock Kernel for the Generalized Fock Space and Generalized Hypergeometric Series

open access: yesJournal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
In this paper, we compute the reproducing kernel Bm,α(z, w) for the generalized Fock space Fm,α2ℂ. The usual Fock space is the case when m = 2. We express the reproducing kernel in terms of a suitable hypergeometric series 1Fq. In particular, we show that there is a close connection between B4,α(z, w) and the error function.

Strongly Pseudoconvex Manifolds and Strongly Pseudoconvex Domains

open access: yesPublications of the Research Institute for Mathematical Sciences, 1984
Let \((X,\psi)\) be a noncompact strongly pseudoconvex manifold. This means that \(\psi\) is a \(C^{\infty}\) exhaustion function on X which is strongly plurisubharmonic outside a compact set. An open relatively compact subset D in X is called an s.p.c.

Projected Composition Operators on Pseudoconvex Domains [PDF]

open access: yesIntegral Equations and Operator Theory, 2021
Let $ \subset \mathbb{C}^n$ be a smooth bounded pseudoconvex domain and $A^2 ( )$ denote its Bergman space. Let $P:L^2( )\longrightarrow A^2( )$ be the Bergman projection. For a measurable $ : \longrightarrow $, the projected composition operator is defined by $(K_ f)(z) = P(f \circ )(z), z \in , f\in A^2 ( ).$ In 1994, Rochberg studied ...

Discs in pseudoconvex domains

open access: yesCommentarii Mathematici Helvetici, 1992
Folgendes Problem wird diskutiert: gibt es zu jedem Punkt \(z^ 0\) eines Gebietes \(G\Subset\mathbb{C}^ N\) \((N\geq 2)\) und zu jeder Richtung \(X\in\mathbb{C}^ N\), \(X\neq 0\), eine eigentliche holomorphe Abbildung \(F:\Delta\to G\) mit: \(F(0)=z^ 0\) und \(F'(0)=\lambda X\), \(\lambda>0\); \(\Delta\) bezeichne hier den offenen Einheitskreis der ...

On Generalized Strongly p‐Convex Functions of Higher Order

open access: yesJournal of Mathematics, Volume 2020, Issue 1, 2020., 2020
The aim of this paper is to introduce the definition of a generalized strongly p‐convex function for higher order. We will develop some basic results related to generalized strongly p‐convex function of higher order. Moreover, we will develop Hermite–Hadamard‐, Fejér‐, and Schur‐type inequalities for this generalization.
