JOURNAL OF APPROXIMATION THEORY 期刊简介
The Journal of Approximation Theory is devoted to advances in pure and applied approximation theory and related areas. These areas include, among others:
• Classical approximation
• Abstract approximation
• Constructive approximation
• Degree of approximation
• Fourier expansions
• Interpolation of operators
• General orthogonal systems
• Interpolation and quadratures
• Multivariate approximation
• Orthogonal polynomials
• Padé approximation
• Rational approximation
• Spline functions of one and several variables
• Approximation by radial basis functions in Euclidean spaces, on spheres, and on more general manifolds
• Special functions with strong connections to classical harmonic analysis, orthogonal polynomial, and approximation theory (as opposed to combinatorics, number theory, representation theory, generating functions, formal theory, and so forth)
• Approximation theoretic aspects of real or complex function theory, function theory, difference or differential equations, function spaces, or harmonic analysis
• Wavelet Theory and its applications in signal and image processing, and in differential equations with special emphasis on connections between wavelet theory and elements of approximation theory (such as approximation orders, Besov and Sobolev spaces, and so forth)
• Gabor (Weyl-Heisenberg) expansions and sampling theory.
《近似理论杂志》致力于纯粹和应用近似理论及相关领域的进展。除其他外,这些领域包括:
• 经典近似
• 抽象近似
• 构造近似
• 近似度
• 傅立叶展开
• 算子的插值
• 一般正交系统
• 插值和正交
• 多元逼近
• 正交多项式
• pad é 逼近
• 有理逼近
• 一个和几个变量的样条函数
• 用欧几里得空间中的径向基函数逼近,在球面上,以及在更一般的流形上
• 与经典调和分析,正交多项式和逼近理论 (与组合数学,数论,表示论,生成函数,形式理论,等等)
·实或复杂函数理论、差分或微分方程、函数空间或谐波分析的近似理论方面
·小波理论及其在信号和图像处理中的应用,在微分方程中,特别强调小波理论与逼近理论元素 (例如逼近阶数,Besov和Sobolev空间等) 之间的联系
• Gabor (Weyl-Heisenberg) 展开和采样理论。
