We construct new Hermite and Lagrange interpolation schemes on the unit sphere in |$\mathbb R^3$|⁠. We give Newton-type formulas for interpolation polynomials and use them to show that the Hermite projectors are the limits of Lagrange projectors when interpolation points coalesce.

在单位球上的Hermite插值法和Lagrange投影仪的极限

我们在| $ \ mathbb R ^ 3 $ |⁠中的单位球面上构造新的Hermite和Lagrange插值方案。我们给出了插值多项式的牛顿式公式,并使用它们来表明当插值点合并时,Hermite投影仪是Lagrange投影仪的极限。
