Abstract
The rational functions are shown to coincide with the compositions of endmarkings, morphisms and inverses of injective morphisms. To represent a rational function tau we need one ednmarking mu(m), two morphisms-alpha-1, alpha-3 and one inverse of an injective morphism-alpha-2 and then tau = mu(m) alpha-1 alpha-2(-1) alpha-3.
