The Thue-Morse shift, Baumslag-Solitar group, and biminimality
Laurent Bartholdi
Call a group action on a topological space \emph{biminimal} if for any points there exists a group element taking arbitrarily close to and whose inverse takes $y…

Groups with ALOGTIME-hard word problems and PSPACE-complete compressed word problems
Laurent Bartholdi, Michael Figelius, Markus Lohrey +1
We give lower bounds on the complexity of the word problem of certain non-solvable groups: for a large class of non-solvable infinite groups, including in particular free groups, G…

Right Angled Artin Groups and partial commutation, old and new
Laurent Bartholdi, Henrika Härer, Thomas Schick
We compute the -central and exponent- series of all right angled Artin groups, and compute the dimensions of their subquotients. We also describe their associated Lie algebra…
