本文证明了Cq中球面上的连续双调正定核是一系列非负系数的圆盘多项式。这些核是真实的球面上所谓正定函数的复类似物,由I。J. Schoenberg(1942,杜克数学杂志,9,96-108)。结果添加到类的功能,其中可以生成径向基函数插值到任意数据的领域。
Abstract Continuous bizonal positive definite kernels on the spheres in C q are shown to be a series of disk polynomials with nonnegative coefficients. These kernels are the complex analogs of the so-called positive definite functions on real spheres introduced and characterized by I. J. Schoenberg (1942, Duke Math. J.9, 96–108). The result adds to the classes of functions from which one can generate radial basis function interpolants to arbitrary data on spheres.
