Brauer webs of finite and affine type
Yaolong Shen, Linliang Song, Weiqiang Wang
We introduce and develop an integral diagrammatic framework for two new monoidal categories, the finite and affine B-web categories. They arise naturally from representation catego…
A Serre-type presentation for quantum supergroups of type A
Weideng Cui, Yaolong Shen
We establish a Serre-type presentation for quantum enveloping superalgebras arising from quantum supersymmetric pairs of type A. We first prove, in arbitrary type, that eva…
Big categorification on towers of classical groups and wreath product groups
Xin Huang, Pengcheng Li, Yaolong Shen
We develop a uniform framework for ``big'' categorification of representation categories of towers of finite classical groups and wreath product groups. We construct actions of sym…
Quantized Coulomb Branches of Separated Cotangent Type and Orthosymplectic Quivers
Yaolong Shen, Changjian Su, Rui Xiong
We propose a definition of the quantized Coulomb branches of separated cotangent type, and prove that the corresponding classical construction recovers the non-cotangent Coulomb br…
On weight modules over truncated shifted iYangians
Yaolong Shen, Linliang Song, Rui Xiong
Truncated shifted iYangians are a family of algebras expected to quantize certain components of affine Grassmannian islices. We introduce orientifold KLRW (oKLRW) algebras associat…
Classifying submodules over monoidal categories
Hadi Salmasian, Alistair Savage, Yaolong Shen
We study the classification of submodules of module categories over monoidal categories, extending ideas of Coulembier on the classification of tensor ideals in monoidal categories…
Quivers with Involutions and Shifted Twisted Yangians via Coulomb Branches
Yaolong Shen, Changjian Su, Rui Xiong
To a quiver with involution, we study the Coulomb branch of the 3d involution-fixed part of the quiver gauge theory. We show that there is an algebra homomorphism…
Affine and cyclotomic -Schur categories via webs
Yaolong Shen, Linliang Song, Weiqiang Wang
We formulate two new -linear diagrammatic monoidal categories, the affine -web category and the affine -Schur category, as well as their respective cyclo…
Quasi-parabolic Kazhdan-Lusztig bases and reflection subgroups
Zachary Carlini, Yaolong Shen
Recently, Wang and the second author constructed a bar involution and canonical basis for a quasi-permutation module of the Hecke algebra associated to a type B Weyl group , whe…
Schur duality and Kazhdan-Lusztig basis expanded
Yaolong Shen, Weiqiang Wang
Expanding the classic works of Kazhdan-Lusztig and Deodhar, we establish bar involutions and canonical (i.e., quasi-parabolic KL) bases on quasi-permutation modules over the type B…
