非线性方程组的一个解的存在性结果(英文)

In [1], S. Smale gave an existence result for finding the solution of the equation F(x)=0 (1) where C(?)R~n is a bounded open connected set, and F∈C~2(C, R~n). Almost simultaneously, H. Keller , C. B. Garcia and F. J. Gould, using the global     

内插的一种新的光滑技术(英文)

Giving two data points P_R(x_k, y_k)and P_(k+i)(x_(k+1), y_(k+1)) in the Cartesian Coordinates System. The knot of the interpolation between P_k and p_(k+1) satisfies the parabolic equation     

一类利用Hadamard卷积定义的解析函数

本文引入了一类由Hadamard卷积定义的解析函数族B_α[β,γ,δ]。给出此类函数的一个充要条件、系数不等式,极值点和偏差定理。最后给出了B_α[β,γ,δ]类函数的星像,凸像半径。     

关于分数算子的一个注记

Let f*g (z) be the convolution or Hadamard product of two functiom f(z) and g(z), that is, if f (z) =z+sum from n=2 to ∞a_nz~n and g(z) =z+sum from n=2 to ∞b_n z_n, then f*g(z)=z+sum from n=2 to ∞a_n b_n z~n (1) Let T denote the class of functions of the form     

Runge—Kutta迭代函数（Ⅱ）

0 IntroductionWe seek methods for obtaining a simple zero x~* of the function f(x).The aim isto develop iterative processes of order p,in the error equationε_(k+1)=Kε_k~p+O(ε_k~(p+1)),as ε_k→0for ε_k=x_k-x~* and Ka function only of the derivatives of f at x~*.The methods to be discussed require one function evaluation and several 1-orderderivative evaluations.They have the advantage when the derivative f~(?) can be ob-     

导弹发射数学模型的一种构造方法

导弹在进入发射状态下,要根据所测得的各种参数经过快速计算,得到一最有利的发射参数。要快速计算就必须寻求一个发射时的数学模型。令以空——地导弹载机发射角的数学模型的建立为例,探讨一种数学模型构造法。
