Graphical splittings of Artin kernels
Danielle Barquinero, Lorenzo Ruffoni, Kaidi Ye
We study Artin kernels, i.e. kernels of discrete characters of right-angled Artin groups, and we show that they decompose as graphs of groups in a way that can be explicitly comput…
Normal form and parabolic dynamics for quadratically growing automorphisms of free groups
Martin Lustig, Kaidi Ye
We present a normal form for outer automorphisms of a non-abelian free group which grow quadratically (measured through the maximal growth of conjugacy classes in u…
When is a polynomially growing automorphism of geometric ?
Kaidi Ye
The main result of this paper is an algorithmic answer to the question raised in the title, up to replacing the given by a positive power. In order to provide…
Partial Dehn twists of free groups relative to local Dehn twists - a dichotomy
Kaidi Ye
A criterion for quadratic or higher growth of group automorphisms is established which are represented by graph-of-groups automorphisms with certain well specified properties. As a…
Quotient and blow-up of automorphisms of graphs of groups
Kaidi Ye
In this paper we study the quotient and "blow-up" of graph-of-groups and of their automorphisms . We show that the existence of such a "bl…
