algebra, there are many characterizations of when it has finite global dimension. In [17],
Shen gave such a characterization using Ringel's resolution quiver. In [11], the second
author, with Zacharia, gave a cyclic homology characterization for when a monomial relation
algebra has finite global dimension. We show directly that these criteria are equivalent for all
Nakayama algebras. Our comparison result also reproves both characterizations. In a …
