LetAbe an Artin algebra. Ifsuch that the global dimension ofis at most 3, then for any, bothBandBopare 2-Igusa–Todorov algebras, where. Letbe projective andsuch that the projective dimension ofPas a rightB-module is at mostn(<∞). IfAis anm-syzygy-finite algebra (resp. anm-Igusa–Todorov algebra), thenBis an (m+n)-syzygy-finite algebra (resp. an (m+n)-Igusa–Todorov algebra); in particular, the finitistic dimension ofBis finite in both cases. Some applications of these results are given.
