Dunkl-Type Operators with Projection Terms Associated to Orthogonal Subsystems in Root System

In this paper, we introduce a new differential-difference operator T_ξ (ξ∈R^N) by using projections associated to orthogonal subsystems in root systems. Similarly to Dunkl theory, we show that these operators commute and we construct an intertwining operator between T_ξ and the directional derivativ...
