This paper is devoted to the construction of a tri-harmonic Green function and Neumann in sector with angle explicitly, as well unit disk. Then related Dirichlet problems for tri-Poisson equation are discussed, respectively.
In this article, a biharmonic Green function and Neumann in sector with angle θ = π/n (n ∈ ℕ) are studied, then we investigate the related Dirichlet problem for bi-Poisson equation, respectively.
The development of information society has deeply changed the style healthcare service delivery and medical access. This study aims to investigate how affects efficiency system in China, explore provincial disparities impact. Based on two-stage Data Envelopment Analysis (DEA) framework, this paper uses a panel data from 31 Chinese provinces 2014 2017 estimate analyze influence efficiency. With index (ISI) increased 0.423 0.488 during sample period, experienced slight decrease 0.892 0.869....
In this paper, Schwarz problem for the inhomogeneous Cauchy-Riemann equation in a rectangle is investigated explicitly. By parqueting reflection principle and Cauchy-Pompeiu formula, modified Schwarz-Poisson representation formula constructed. particular, boundary behaviors related Schwarz-type Pompeiu-type operators at corner points are discussed detail.
In this paper, we focus on single periodic Riemann problems for a class of meta-analytic functions, i.e. null-solutions to polynomially Cauchy–Riemann equation. We first establish decomposition theorems functions. Then, give series expansion and derive generalised Liouville them. Next, introduce definition order functions at infinity, characterise their growth infinity. Finally, applying the theorem get explicit expressions solutions condition solvability with finite
In this article, Haseman boundary value problems (BVPs) for a class of metaanalytic functions with different shifts on the unit circumference are investigated. The expression solution and condition solvability problem obtained by reducing to an equivalent system two BVPs analytic functions.
In this paper, we give a general discussion for the Schwarz and Dirichlet problems Cauchy–Riemann equation, then Neumann Poisson equation are also explicitly solved in fan-shaped domain with angle , α ≥ 1.
Abstract In this article, some mixed boundary value problems (BVPs) on the unit circumference for pairs of a metaanalytic function and an analytic are discussed. Using relationship between polyanalytic function, expression solution condition solvability problem obtained by reducing to equivalent system Haseman BVP Hilbert function.

When designing the sample scheme, it is important to determine size. The survey accuracy and cost of sampling method should be considered comprehensively. In this article, we discuss determining size complex successive with rotation for sensitive issue deduce formulas optimal under two‐stage stratified by using Cauchy‐Schwartz inequality, respectively, so as minimize given errors cost.
Background Patients with cognitive impairment have great inconvenience in their cognitive, recognition, and activity abilities, specifically manifested memory disorders, attention perception learning disabilities, which greatly hinder communication, life abilities. The use of actively oriented intervention treatment methods research has an improved effect on patients. Subjects Methods Firstly, 48 patients a certain hospital were selected randomly divided into control group 24 cases...
In this article,we first give a modified Schwarz-Pompeiu formula in general sector ring by proper conformal mappings, and obtain the solution of Schwarz problem for Cauchy-Riemann equation explicit forms. Furthermore, class integral operators is introduced together with their properties. Finally, virtue these operators, problems inhomogeneous polyanalytic generalized are investigated, respectively.
