Abstract

In \cite{DFW} and \cite{Fu07}, little qq-Schur algebras were introduced as homomorphic images of the infinitesimal quantum groups. In this paper, we will investigate representations of these algebras. We will classify simple modules for little qq-Schur algebras and classify semisimple little qq-Schur algebras. Moreover, through the classification of the blocks of little qq-Schur algebras for n=2n=2, we will determine little qq-Schur algebras of finite representation type in the odd roots of unity case.
