An explicit formula for the inverse of a factorial Hankel matrix

Numerical Analysis 2021-02-02 v2

Abstract

We consider the n×nn\times n Hankel matrix HH whose entries are defined by Hij=1/si+jH_{ij}=1/s_{i+j} where sk=(k1)!s_k=(k-1)! and prove that HH is invertible for all nNn\in\mathbb{N} by providing an explicit formula for its inverse matrix.
