报告摘要：An enhanced algebraic group is a product variety $GL(V)\times V$, endowed with an enhanced cross product. Associated with a natural tensor representation, there are naturally Levi and parabolic Schur algebras respectively. We precisely investigate their structures, and study the dualities on the enhanced tensor representations for variant groups and algebras. In this course, an algebraic model  of  so-called degenerate double Hecke algebras (dDHA) is produced, and becomes a powerful implement.  With aid of  this,  we obtain a parabolic Schur-Weyl duality.  The parabolic Schur subalgebra turns out to have only one block. The Cartan invariants for this algebra are precisely determined. This is a joint work with Yunpeng Xue and Yufeng Yao.
