【 摘 要 】

The purpose of this short note is to understand the split Grothendieck ring of the Deligne category (Rep) under bar (GL(t)). We give a formula for the class of an indecomposable object in terms of exterior powers of the tautological object and its dual. (C) 2020 Elsevier Inc. All rights reserved.
