Slim cyclotomic q-Schur algebras
Bangming Deng, Jie Du, Guiyu Yang
We construct a new basis for a slim cyclotomic -Schur algebra $\cysSr$ via symmetric polynomials in Jucys--Murphy operators of the cyclotomic Hecke algebra $\cysHr$. We show tha…
Affine quasi-heredity of affine Schur algebras
Bangming Deng, Guiyu Yang
In this paper we prove that the affine Schur algebra $\whS(n,r)$ is affine quasi-hereditary. This result is then applied to show that $\whS(n,r)$ has finite global dimension and it…
Affine cellularity of S_triangle(2,2)
Guiyu yang
In this paper we prove that the affine Schur algebra $\s$ is affine cellular over $\bbq$. As an application, we prove it is of finite global dimension.
Projective modules of -Schur algebras
Bernt Tore Jensen, Xiuping Su, Guiyu Yang
We study the structure of the -Schur algebra following the geometric construction of by Jensen and Su \cite{JS}. The main results are the construction an…
