As title, I would like to know the known upper bound for the $l^1$ norm for inverse of Vandermonde matrix. A quick search gives this paper by Gautschi 40 years ago, but it deals with the infinity norm instead. Thanks!
Motivation: Part 2 of this problem
springerlink.comis broken. It should probably point to the following one: Gautschi, Walter, Norm estimates for inverses of Vandermonde matrices, Numer. Math. 23, 337–347 (1975). Zbl 0304.65031. – The Amplitwist May 21 '22 at 19:38
