Erratum to: Classical W-Algebras and Generalized Drinfeld–Sokolov Hierarchies for Minimal and Short Nilpotents

Abstract

There is an error in Sect. 6.2 of the original article in the computation of equations of the generalized Drinfeld–Sokolov hierarchy associated to the minimal nilpotent element f of the Lie algebra g = sln, n ≥ 3, corresponding to the unique (up to a constant factor) non-zero central element c ∈ g f0 (such c exists for minimal f only in the case g = sln, n ≥ 3).
