摘要
本文讨论了2π周期和反周期函数在等距结点上的一类Birkhoff型2-周期三角和仿三角插值问题,给出了此问题有解的充要条件,并构造出插值基。
In this paper,a kind of Birkhoff type 2-periodic trigonometric and paratrigonometric interpolation problems with equidistant nodes for 2π-periodic and antiperiodic functions are discussed.We give the necessary and sufficient conditions for the solvable case of these interpolation problems.The expressions of the interpolation basis are constructed.
