چکیده
We introduce the notions of τ -exceptional and signed sequences for any finite dimensional algebra. prove that a fixed algebra rank n , positive integer t ≤ there is bijection between set length (basic) ordered support -rigid objects with indecomposable direct summands. If hereditary, our coincide exceptional sequences. The latter were recently introduced by Igusa Todorov, who constructed similar in hereditary setting.

Exceptional Sequences and Clusters
We show that exceptional sequences for hereditary algebras are characterized by the fact that the product of the corresponding reflections is the inverse Coxeter element in the Weyl group. We use this result to give a new combinatorial characterization of clusters tilting sets in the cluster category in the case where the hereditary algebra is of finite type.
متن کاملExceptional Sequences and Derived Autoequivalences
We prove a general theorem that gives a non trivial relation in the group of derived autoequivalences of a variety (or stack) X, under the assumption that there exists a suitable functor from the derived category of another variety Y admitting a full exceptional sequence. Applications include the case in which X is Calabi-Yau and either X is a hypersurface in Y (this extends a previous result b...

متن کاملMaximal Green Sequences of Exceptional Finite Mutation Type Quivers
Maximal green sequences are particular sequences of mutations of quivers which were introduced by Keller in the context of quantum dilogarithm identities and independently by Cecotti–Córdova–Vafa in the context of supersymmetric gauge theory. The existence of maximal green sequences for exceptional finite mutation type quivers has been shown by Alim–Cecotti–Córdova–Espahbodi–Rastogi–Vafa except...
متن کاملCombinatorial Aspects of Exceptional Sequences on (rational) Surfaces
We investigate combinatorial aspects of exceptional sequences in the derived category of coherent sheaves on smooth and complete algebraic surfaces with pg = q = 0. We show that to any such sequence there is canonically associated a complete toric surface whose torus fixpoints are either smooth or cyclic T-singularities (in the sense of Wahl) of type 1 r2 (1, kr − 1). We also show that any exce...
