On solvable subgroups of automorphism groups of right-angled Artin groups
Matthew B. Day
For any right-angled Artin group, we show that its outer automorphism group contains either a finite-index nilpotent subgroup or a nonabelian free subgroup. This is a weak Tits alt…

Extensions of Johnson's and Morita's homomorphisms that map to finitely generated abelian groups
Matthew B. Day
We extend each higher Johnson homomorphism to a crossed homomorphism from the automorphism group of a finite-rank free group to a finite-rank abelian group. We also extend each Mor…
