Every type A quiver locus is a Kazhdan-Lusztig variety
Jiajun Xu, Guanglian Zhang
The Zariski closures of the orbits for representations of type A Dynkin quivers under the action of general linear groups (i.e. quiver loci) exhibit a profound connection with Schu…
The defining equations of a class of Richardson and flag varieties on Sp
Jiajun Xu, Guanglian Zhang
This paper aims to focus on Richardson varieties on symplectic groups, especially their combinatorial characterization and defining equations. Schubert varieties and opposite Schub…
Gröbner--Shirshov bases for commutative dialgebras
Yuqun Chen, Guangliang Zhang
We establish Gröbner--Shirshov bases theory for commutative dialgebras. We show that for any ideal of , has a unique reduced Gröbner--Shirshov basis, where i…
Free Products of digroups
Guangliang Zhang, Yuqun Chen, Zerui Zhang
We construct the free products of arbitrary digroups, and thus we solve an open problem of Zhuchok.
A construction of free digroup
Guangliang Zhang, Yuqun Chen
We give a construction of a free digroup on a set and formulate the halo and the group parts of . We prove that is isomorphic to if and only if $card…
Rational Ringel-Hall algebras, Hall polynomials of affine type and Canonical bases
Guanglian Zhang
In this paper, the rational Ringel-Hall algebras for tame quivers are introduced and are identified with the positive part of the quantum extended Kac-Moody algebras. By using the…
