THE CAUCHY TYPE INTEGRAL FOR M-ANALYTIC FUNCTION AND ITS APPLICATION

In this paper, the Cauchy type integral for M-analytic function is investigated which is by definition the regular solution of the elliptic system f_x+Mf_y=0, where M is a constant m×m matrix without any real eigenvalues and f is an m×q matrix.

基于有界度抛物复形的解析函数边值问题

该文讨论使用Circle Packing 方法来考虑解析函数边值问题. 寻求满足给定边界条件的解析函数, 是许多理论和实际问题中应用极为广泛的重要问题. 该文使用有界度的Circle Packing来构造给定区域上满足一定边界条件的解析函数, 为此首先讨论了 Circle Packing 映射与经典多项式之间的关系, 并在此基础上证明离散序列对解析函数的收敛性. 这个结果扩展了Carter和Rodin以及Dubejko早期使用正则6-packing取得的结果.

RESEARCH ANNOUNCEMENTS On a Spectrum Problem for Analytic Function

1 IntroductionLet Ω be the unit disk {z: |z| < 1} in the complex plane C. In this paper, we consider thefollowing boundary value problem: Find cot a λ and the analytic function u(z) in the unit diskΩ such that they satisfy the boundary conditionwhere denotes the outer normal derivative of μ.The problem (l) has background in physics and mechanics [2,3]. To our knowledge it seemsthat few work have been done. In some cases one usually assumes that λ is sufficiently small,e.g. for second or…

具有超解析Cauchy核的奇异积分方程

We investigate the solvability and the solving methods of singular integral equation with hyperanalytic Cauchy kernel(?) where α,k are hypercomplex functions in the sense of A. Douglis, φ is the unknown function. We prove that the equation Kφ=f , under certain conditions, is Noetherian. And a direct method to solve Kφ = f whenα and k are the boun dary values of hyperanalytic functions is given.
