We investigate quantitative aspects of the LEF property for subgroups of the topological full group ⟦ ⟧ of a two-sided minimal subshift over a finite alphabet, measured via the LEF growth function. We show that the LEF growth of ⟦ ⟧′ may be bounded from above and below in terms of the recurrence function and the complexity function of the subshift, respectively. As an application, we construct groups of previously unseen LEF growth types, and exhibit a continuum of finitely generated LEF groups… Expand

Full residual finiteness growths of nilpotent groups
Full residual finiteness growth of a finitely generated group G measures how efficiently word metric n-balls of G inject into finite quotients of G. We initiate a study of this growth over the classExpand
Some remarks on topological full groups of Cantor minimal systems
Giordano, Putnam and Skau showed that topological full groups of Cantor minimal systems are complete invariants for flip conjugacy. We will completely determine the structure of normal subgroups ofExpand
Residual finiteness growths of Lamplighter groups
Residual finiteness growth gives an invariant that indicates how well-approximated a finitely generated group is by its finite quotients. We briefly survey the state of the subject. We then improveExpand
ON ALGEBRAIC PROPERTIES OF TOPOLOGICAL FULL GROUPS
In the paper we discuss the algebraic structure of topological full group [[T ]] of a Cantor minimal system (X,T ). We show that the topological full group [[T ]] has the structure similar to a unionExpand
Full groups and soficity
First, we answer a question of Pestov, by proving that the full group of a sofic equivalence relation is a sofic group. Then, we give a short proof of the theorem of Grigorchuk and Medynets that theExpand
Cantor systems, piecewise translations and simple amenable groups
We provide the rst examples of nitely generated simple groups that are amenable (and innite). To this end, we prove that topological full groups of minimal systems are amenable. This follows from aExpand
