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…

Decomposition matrices of cyclotomic -web categories

Linliang Song, Weiqiang Wang

We develop the cellular structures for the endomorphism algebras of cyclotomic -webs, which form a new family of quantum algebras sitting in between cyclotomic Hecke algebras an…

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…

Affine web of type Q

Linliang Song, Xingyu Wang

We introduce a new diagrammatic -linear monoidal supercategory , the affine web supercategory of type , where is a commutative ring of characteristi…

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…

Affine and cyclotomic Schur categories

Linliang Song, Weiqiang Wang

Using the affine web category introduced in a prequel as a building block, we formulate a diagrammatic -linear monoidal category, the affine Schur category, for any commutat…

Affine and cyclotomic webs

Linliang Song, Weiqiang Wang

Generalizing the polynomial web category, we introduce a diagrammatic -linear monoidal category, the affine web category, for any commutative ring . Integral bases co…
