A note concerning the invertibility of certain alternant matrices

Jeff Ledford

This brief note concerns the invertibility of certain alternant matrices. In particular those that consisting of polynomials and products of polynomials and logarithms are shown to…

On non-local approximation properties of the binomial power functions $(1 + x^{q})^{r}$

Brock Erwin, Jeff Ledford, Kira Pierce

This note mainly concerns the binomial power function, defined as $(1 + x^{q})^{r}$ . We construct systems of polynomials related to non-local approximation, which allows us to establis…
