DESCRIPTION:Title: Cyclic tridiagonal pairs\, higher order Onsager algebras
  and othogonal polynomials.\n\nAbstract: The concept of cyclic tridiagonal
  pairs is introduced\, and explicit examples are given. For a fairly gener
 al class of cyclic tridiagonal pairs with cyclicity N\, we associate a pai
 r of `divided polynomials'. The properties of this pair generalize the one
 s of tridiagonal pairs of Racah type. The algebra generated by the pair of
  divided polynomials is identified as a higher-order generalization of the
  Onsager algebra. It can be viewed as a subalgebra of the q-Onsager algebr
 a for a proper specialization at q the primitive 2Nth root of unity. Ortho
 gonal polynomials beyond the Leonard duality introduced by Tsujimoto\, Vin
 et and Zhedanov are revisited in light of this framework. Joint work with 
 A.M Gainutdinov and T.T. Vu. arXiv:1607.00606 [math.QA]\n
