Abstract
We construct an action of the Hecke algebra on a quotient of the polynomial ring , where . The dimension of our quotient ring is the number of -block ordered set partitions of . This gives a quantum analog of a construction of Haglund-Rhoades-Shimozono and interpolates between their result at and work of Huang-Rhoades at .
