  • Double Affine Hecke Algebras of Rank 1 and the Z₃-Symmetric Askey-Wilson Relations 
    Ito, T.; Terwilliger, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We consider the double affine Hecke algebra H=H(k₀,k₁,k₀v,k₁v;q) associated with the root system (C₁v,C₁). We display three elements x, y, z in H that satisfy essentially the Z₃-symmetric Askey-Wilson relations. We obtain ...
  • On a Certain Subalgebra of Uq(sl₂) Related to the Degenerate q-Onsager Algebra 
    Hattai, T.; Ito, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    In [Kyushu J. Math. 64 (2010), 81-144], it is discussed that a certain subalgebra of the quantum affine algebra Uq(sl₂) controls the second kind TD-algebra of type I (the degenerate q-Onsager algebra). The subalgebra, which ...
