Frobenius–Perron dimension via tau$\tau$

Abstract

From the perspective of

tau $\tau$ τ
-tilting theory, we study Frobenius–Perron dimensions of finite-dimensional algebras. First, we evaluate the Frobenius–Perron dimensions of
tau $\tau$ τ
-tilting finite algebras by a combinatorial method in
tau $\tau$ τ
-tilting theory. Second, we give an upper bound for the Frobenius–Perron dimension of
tau $\tau$ τ
-tilting finite algebras of tame representation type. Third, we determine the Frobenius–Perron dimensions of Nakayama algebras and generalized preprojective algebras of Dynkin type in the sense of Geiß–Leclerc–Schröer.
