# Embedding of the rank 1 DAHA into Mat(2,Tq) and its automorphisms

chapter

posted on 06.05.2016, 11:04 by Marta MazzoccoIn this review paper we show how the Cherednik algebra of type Č1C1 appears naturally as quantisation of the group algebra of the monodromy group associated to the sixth Painlevé equation. This fact naturally leads to an embedding of the Cherednik algebra of type Č1C1 into Mat(2,Tq), i.e. 2×2 matrices with entries in the quantum torus. For q=1 this result is equivalent to say that the Cherednik algebra of type Č1C1 is Azumaya of degree 2 [31]. By quantising the action of the braid group and of the Okamoto transformations on the monodromy group associated to the sixth Painlevé equation we study the automorphisms of the Cherednik algebra of type Č1C1 and conjecture the existence of a new automorphism. Inspired by the confluences of the Painlevé equations, we produce similar embeddings for the confluent Cherednik algebras HV, HIV, HIII, HII and HI, defined in [27].
