Abstract

Abstract We fix an error on a $3$ -cocycle in the original version of the paper ‘Endoscopy for Hecke categories, character sheaves and representations’. We give the corrected statements of the main results.

Highlights

  • We fix an error on a 3-cocycle in the original version of the paper ‘Endoscopy for Hecke categories, character sheaves and representations’

  • The published version of [1] contains an error that led to the wrong conclusion on a certain 3-cocycle that appears in the monoidal structure of the monodromic Hecke category

  • The mistake in the is that, the character sheaf L becomes trivial when restricted to T (Fq), the trivialisation cannot necessarily be made WL-equivariantly

Introduction

Abstract We fix an error on a 3-cocycle in the original version of the paper ‘Endoscopy for Hecke categories, character sheaves and representations’. The published version of [1] contains an error that led to the wrong conclusion on a certain 3-cocycle that appears in the monoidal structure of the monodromic Hecke category. The mistake in the is that, the character sheaf L becomes trivial when restricted to T (Fq), the trivialisation cannot necessarily be made WL-equivariantly.
