Abstract
Consider the set of finite words on a totally ordered alphabet with $q$
letters. We prove that the distribution of the length of the standard right
factor of a random Lyndon word with length $n$, divided by $n$, converges to:
$$\mu(dx)=\frac1q \delta_1(dx) + q-1q 1_0,1)(x)dx,$$ when
$n$ goes to infinity. The convergence of all moments follows. This paper
completes thus the results of Bassino, giving the asymptotics of the
mean length of the standard right factor of a random Lyndon word with length
$n$ in the case of a two letters alphabet.
