Abstract
We show an instance of the cyclic sieving phenomenon on annular noncrossing permutations with given cycle types. We define annular -Kreweras numbers, annular -Narayana numbers, and annular -Catalan number, all of which are polynomials in . We then show that these polynomials exhibit the cyclic sieving phenomenon on annular noncrossing permutations. We also show that a sum of annular -Kreweras numbers becomes an annular -Narayana number and a sum of -Narayana numbers becomes an annular -Catalan number.
