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 computed from the underlying graph. When the underlying graph is chordal we

Un automorphisme (extérieur) $phi $ d'un groupe libre $F_n$ de rang fini $ngeq 2$ est dit géométrique s'il est induit par un homéomorphisme d'une surface. La question à laquelle nous intéressons est la suivante: Quels sont les automorphismes de

We present a normal form for outer automorphisms $\phi$ of a non-abelian free group $F_N$ which grow quadratically (measured through the maximal growth of conjugacy classes in $F_N$ under iteration of $\phi$). In analogy to the known normal form for

The main result of this paper is an algorithmic answer to the question raised in the title, up to replacing the given $\hat{\phi} \in Out(F_n)$ by a positive power. In order to provide this algorithm, it is shown that every polynomially growing autom

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 consequence, it is derived (using results of a previous paper of the

In this paper we study the quotient and "blow-up" of graph-of-groups $\cal{G}$ and of their automorphisms $H: \cal{G} \rightarrow \cal{G}$. We show that the existence of such a "blow-up" of $\bar{H}: \bar{\cal{G}} \rightarrow \bar{\cal{G}}$ relative

We present an improved incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) system based on an iterative retrieval algorithm for the simultaneous detection of atmospheric nitrous acid (HONO) and nitrogen dioxide (NO2). The conventio

Nitrous acid (HONO), an important precursor of the hydroxyl radical (OH), plays a key role in atmospheric chemistry, but its sources are still debated. The production of HONO on aerosol surfaces or on ground surfaces in nocturnal atmospheres remains
