设A是代数闭域上的Noether完全基本半完全代数,C=A°是其对偶余代数。如果A是Artin-Schelter正则的,则A的局部上同调同构于扭曲双模1Cσ*的移位,其中σ是余代数自同构。这证明了A的平衡对偶化复形是扭曲双模σ*A1的移位。如果σ是内自同构,则A是Calabi-Yau。在附录中证明了Artin余代数上拟有限余模的有界导范畴的一个对偶定理。
Let A be a noetherian complete basic semiperfect algebra over an algebraically closed field, and C = A°be its dual coalgebra. If A is Artin–Schelter regular, then the local cohomology of A is isomorphic to a shift of twisted bimodule 1 C σ* with σ a coalgebra automorphism. This yields that the balanced dualinzing complex of A is a shift of the twisted bimodule σ* A 1. If σ is an inner automorphism, then A is Calabi–Yau. An appendix is included to prove a duality theorem of the bounded derived category of quasi-finite comodules over an artinian coalgebra.
