Resumen

Sean R un álgebra Artin-Schelter regular y A = σ(R)⟨x1,...,xn   una extensión PBW torcida cuasi-conmutativa graduada sobre R. En este artículo se describe el automorfismo de Nakayama de A usando el automorfismo de
Nakayama del anillo de coeficientes R. También se calcula explícitamente el automorfismo de Nakayama de algunas extensiones PBW torcidas.
