摘要:

作者近期发展了一种与平移格点相关的离散傅里叶分析。它允许两个格点,一个决定积分域,另一个决定指数函数族。在覆盖R^2的格点情况下,讨论了格点的可能选择,并得到了关于三角和代数多项式的求积与插值的若干新结果。

英文摘要:

A discrete Fourier analysis associated with translation lattices is developed recently by the authors. It permits two lattices, one determining the integral domain and the other determining the family of exponential functions. Possible choices of lattices are discussed in the case of lattices that tile $\RR^2$ and several new results on cubature and interpolation by trigonometric, as well as algebraic, polynomials are obtained.
