Cellularity of endomorphism algebras of tilting objects

نویسندگان

چکیده

We show that, in a highest weight category with duality, the endomorphism algebra of tilting object is naturally cellular algebra. Our proof generalizes recent construction Andersen, Stroppel, and Tubbenhauer [4] . This result raises question whether all algebras can be realized this way. The also works without presence duality yields standard bases, sense Du Rui, which have similar combinatorial features to bases. As an application, we obtain bases—and thus general theory “cell modules”—for Hecke associated finite complex reflection groups (as introduced by Broué, Malle, Rouquier) via O rational Cherednik For real these bases are cellular.

amenability of banach algebras

chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...

Endomorphism Algebras of Maximal Rigid Objects in Cluster Tubes

Given a maximal rigid object T of the cluster tube, we determine the objects finitely presented by T . We then use the method of Keller and Reiten to show that the endomorphism algebra of T is Gorenstein and of finite representation type, as first shown by Vatne. This algebra turns out to be the Jacobian algebra of a certain quiver with potential, when the characteristic of the base field is no...

Endomorphism algebras of Jacobians

where K is a subfield of even index at most 10 in a primitive cyclotomic field Q(ζp), or a subfield of index 2 in Q(ζpq) or Q(ζpα ). This result generalizes previous work of Brumer, Mestre, and Tautz-Top-Verberkmoes. Our curves are constructed as branched covers of the projective line, and the endomorphisms arise as quotients of double coset algebras of the Galois groups of these coverings. In ...

Endomorphism Algebras of Superelliptic Jacobians

As usual, we write Z,Q,Fp,C for the ring of integers, the field of rational numbers, the finite field with p elements and the field of complex numbers respectively. If Z is a smooth algebraic variety over an algebraically closed field then we write Ω(Z) for the space of differentials of the first kind on Z. If Z is an abelian variety then we write End(Z) for its ring of (absolute) endomorphisms...

Stratifying Endomorphism Algebras Associated to Hecke Algebras

Let G be a nite group of Lie type and let k be a eld of characteristic distinct from the de ning characteristic of G. In studying the non-describing representation theory of G, the endomorphism algebra S(G;k) = EndkG( L J ind G PJ k) plays an increasingly important role. In type A, by work of Dipper and James, S(G; k) identi es with a q-Schur algebra and so serves as a link between the represen...
