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》致力于纯近似理论、应用近似理论及相关领域的进展。这些领域包括但不限于：

• 抽象近似

• 构造性近似

• 近似度

• 傅里叶展开

• 算子插值

• 一般正交系统

• 插值和求积

• 多元近似

• 正交多项式

• Padé 近似

• 有理近似

• 一元和多元样条函数

• 在欧几里得空间、球面和更一般的流形上用径向基函数近似

•与经典谐波分析、正交多项式和近似理论（与组合学、数论、表示论、生成函数、形式理论等相对）密切相关的特殊函数

• 实函数或复函数理论、函数论、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以及微分方程中的应用，特别强调小波理论与近似理论元素（如近似阶、Besov 和 Sobolev 空间等）之间的联系

• Gabor（Weyl-Heisenberg）展开和采样理论。
