Dec 31, 2019 at 3:34 | comment | added | Noam D. Elkies | What do you want to know about these determinants? Sticking to $D(n,k)$, we easily have $D_{n,k}=0$ if $n>k+1$, and there seems to be a nice factorization for $D_{k+1,k}$; also there have been several Mathoverflow questions and answers about the sign of $D_{n,k}$, even for $k \notin \bf Z$. On the other hand if you fix $n$ and vary $k$ it's some complicated signed sum of $n!$ or so $k$-th powers. | |
