Hecke algebras and edge contractions

Yiqiang Li

We establish an embedding from the Hecke algebra associated with the edge contraction of a Coxeter system along an edge to the Hecke algebra associated with the original Coxeter sy…

Critical Cohomological Hall Algebra and Edge Contraction

Yiqiang Li, Jie Ren

We study the behaviors of cohomological Hall algebras and relevant subjects under an edge contraction. Given a quiver with potential and fix an arrow, the edge contraction is a way…

Quantum groups and edge contractions

Yiqiang Li

We study the behaviors of quantum groups under an edge contraction. We show that there exists an explicit embedding induced by an edge contraction operation. We further conjecture…

Embeddings among quantum affine

Yiqiang Li

We establish an explicit embedding of a quantum affine into a quantum affine . This embedding serves as a common generalization of two natura…

Quasi-split symmetric pairs of and Steinberg varieties of classical type

Yiqiang Li

We provide a Lagrangian construction for the fixed-point subalgebra, together with its idempotent form, in a quasi-split symmetric pair of type . This is obtained inside t…

Quasi-split symmetric pairs of and their Schur algebras

Yiqiang Li, Jieru Zhu

We establish explicit isomorphisms of two seemingly-different algebras, and their Schur algebras, arising from the centralizers of two different type B Weyl group actions in Schur-…
