## Cyclic sieving for reduced reflection factorizations of the Coxeter element

Given a factorization \(t_1\cdots t_n=c\) of some element \(c\) in a group, there are various natural cyclic operations we can apply on it; one of them is given by \(\Psi:(t_1,\cdots,t_n)\rightarrow (c\ t_n\ c^{-1},t_1,\cdots, t_{n-1})\). A common question is then to ...

## Binary pattern of length greater than 14 are abelian-2-avoidable

Summary: Two words u and v are abelian equivalent if they are permutation of each other ("aabc" and "baca" are abelian equivalent). Let w be a word and P= P1...Pn (where the Pi are the letters of P) a pattern (a word over another alphabet), we say that w ...
