Corrigendum: Low degree Hurwitz stacks in the Grothendieck ring (Compositio Math. 160 (2024), 1784–1849)

Key Points

• The aim is to correct an error in a previously published theorem about Hurwitz stacks.
• Added the omitted hypothesis regarding covers being arithmetically Gorenstein.
• Clarified the implications of this hypothesis for the theorem.
