Local to global principle for higher moments over function fields
Andy Hsiao, Junhong Ma Blackmer, Severin Schraven +1
We establish a local to global principle for higher moments over holomorphy rings of global function fields and use it to compute the higher moments of rectangular unimodular matri…
