Harish-Chandra isomorphism for cyclotomic double affine Hecke algebras
Joshua Jeishing Wen
We confirm a conjecture of Braverman--Etingof--Finkelberg that the spherical subalgebra of their cyclotomic double affine Hecke algebra (DAHA) is isomorphic to a quantized multipli…

Quantum Harish-Chandra isomorphism for the double affine Hecke algebra of
Joshua Jeishing Wen
We prove that for generic parameters, the quantum radial parts map of Varagnolo and Vasserot gives an isomorphism between the spherical double affine Hecke algebra of and a…
