Graded quantum cluster algebras of infinite rank as colimits

Jan E. Grabowski, Sira Gratz

We provide a graded and quantum version of the category of rooted cluster algebras introduced by Assem, Dupont and Schiffler and show that every graded quantum cluster algebra of i…

A quantum analogue of the dihedral action on Grassmannians

Justin M. Allman, Jan E. Grabowski

In recent work, Launois and Lenagan have shown how to construct a cocycle twisting of the quantum Grassmannian and an isomorphism of the twisted and untwisted algebras that sends a…

Quantum cluster algebra structures on quantum Grassmannians and their quantum Schubert cells: the finite-type cases

Jan E. Grabowski, Stéphane Launois

We exhibit quantum cluster algebra structures on quantum Grassmannians and their quantum Schubert cells, as well as on , and $K_q[Gr(3,8…

Examples of quantum cluster algebras associated to partial flag varieties

Jan E. Grabowski

We give several explicit examples of quantum cluster algebra structures, as introduced by Berenstein and Zelevinsky, on quantized coordinate rings of partial flag varieties and the…

Braided-Lie bialgebras associated to Kac-Moody algebras

Jan E. Grabowski

Braided-Lie bialgebras have been introduced by Majid, as the Lie versions of Hopf algebras in braided categories. In this paper we extend previous work of Majid and of ours to show…

Braided enveloping algebras associated to quantum parabolic subalgebras

Jan E. Grabowski

Associated to each subset of the nodes of a Dynkin diagram is a triangular decomposition of the corresponding Lie algebra into three subalgebras $\widetilde{…
