-trees and laminations for free groups II: The dual lamination of an -tree
Thierry Coulbois, Arnaud Hilion, Martin Lustig
Abstract
This is the second part of a series of three articles which introduce laminations for free groups (see math.GR/0609416 for the first part). Several definition of the dual lamination of a very small action of a free group on an -tree are given and proved to be equivalent.
