Multidimensional matrix inversions and elliptic hypergeometric series on root systems

Artikel i vetenskaplig tidskrift, 2020

Multidimensional matrix inversions provide a powerful tool for studying multiple hypergeometric series. In order to extend this technique to elliptic hypergeometric series, we present three new multidimensional matrix inversions. As applications, we obtain a new Ar elliptic Jackson summation, as well as several quadratic, cubic and quartic summation formulas.
