Description:
For every irreducible hyperbolic automorphism of F N (i.e. the analog of a pseudo-Anosov mapping class) it is shown that the algebraic lamination dual to the forward limit tree T + () is obtained as ‘diagonal closure’ of the support of the backward limit current μ – (). This diagonal closure is obtained through a finite procedure analogous to adding diagonal leaves from the complementary components to the stable lamination of a pseudo-Anosov homeomorphism. We also give several new characterizations as well as a structure theorem for the dual lamination of T + (), in terms of Bestvina–Feighn–Handel's ‘stable lamination’ associated to .
