Schur-Weyl duality for infinitesimal q-Schur algebras s(q)(2, r)(1)

Using the result of [S.R. Doty, D.K. Nakano, K.M. Peters, Polynomial representations of Frobenius kernels of GL, in: Contemp. Math., vol. 194, 1996, pp. 57-67; S. König, C. Xi, When is a cellular algebra quasi-hereditary? Math. Ann. 315 (1999) 281-293], we prove that a non-semisimple infinitesimal S...
