First, we evaluate the Frobenius--Perron dimensions of $\\tau$-tilting finite algebras by a combinatorial method in $\\tau$-tilting theory. Secondly, we give the upper bound of the Frobenius--Perron dimension for a $\\tau$-tilting finite algebra of tame representation type. Thirdly, we determine the Frobenius--Perron dimensions of Nakayama algebras and generalized preprojective algebras of Dynkin type in the sense of Geiss--Leclerc--Schr\\\"oer.", "revisions": [ { "version": "v1", "updated": "2025-01-09T08:11:25.000Z" } ], "analyses": { "keywords": [ "tilting theory", "tilting finite algebra", "study frobenius-perron dimensions", "tame representation type", "upper bound" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
