On the Pseudoperiodic Extension of u^l = v^m w^n

Abstract

We investigate the solution set of the pseudoperiodic extension of the classical Lyndon and Sch"utzenberger word equations. Consider u_1 ... u_l = v_1 ... v_m w_1 ... w_n, where u_i is in {u, theta(u)} for all 1 = 12 or m,n >= 5 and either m and n are not both even or not all u_i\u27s are equal, all solutions are pseudoperiodic
