Branch actions and the structure lattice
Jorge Fariña-Asategui, Rostislav Grigorchuk
J. S. Wilson proved in 1971 an isomorphism between the structural lattice associated to a group belonging to his second class of groups with every proper quotient finite and the Bo…
SFT covers for actions of the first Grigorchuk group
Rostislav Grigorchuk, Ville Salo
We study symbolic dynamical representations of actions of the first Grigorchuk group , namely its action on the boundary of the infinite rooted binary tree, its representation i…
On maximal subgroups of ample groups
Rostislav Grigorchuk, Yaroslav Vorobets
The paper is concerned with maximal subgroups of the ample (better known as topological full) groups of homeomorphisms of totally disconnected compact metrizable topological spaces…
On the structure of finitely generated subgroups of branch groups
Dominik Francoeur, Rostislav Grigorchuk, Paul-Henry Leemann +1
We describe the block structure of finitely generated subgroups of branch groups with the so-called subgroup induction property, including the first Grigorchuk group …
