title = "On the length of the minimum solution of word equations in one variable",

abstract = "We show the tight upperbound of the length of the minimum solution of a word equation L = R in one variable, in terms of the differences between the positions of corresponding variable occurrences in L and R. By introducing the notion of difference, the proof is obtained from Fine and Wilf's theorem. As a corollary, it implies that the length of the minimum solution is less than N = |L| + |R|.",
