Errata \`a ``Sur les repr\'esentations non ramifi\'ees des groupes r\'eductifs $p$-adiques; l'exemple de ${\rm GSp}(4)$''

TL;DR

This paper provides corrections to previous work on unramified representations of reductive p-adic groups, specifically addressing errors related to involutions and the GSp(4) group, refining the understanding of these representations.

Contribution

It identifies and corrects two specific errors in earlier research on unramified representations of reductive p-adic groups, enhancing the accuracy of the theoretical framework.

Findings

Corrected the study of an involution on irreducible unramified representations

Fixed errors in the description of GSp(4) representations

Improved the theoretical understanding of unramified p-adic group representations

Abstract

We correct two errors in the paper "Sur les repr\'esentations non ramifi\'ees des groupes r\'eductifs p-adiques; l'exemple de GSp(4)": the first in the study of an involution on the irreducible unramified representations of a semi-simple group, the second in the description of representations of the group GSp(4).
