A Sofic Group Away from Amenable Groups
We give an example of a sofic group, which is not a limit of amenable groups.
متن کاملEntropy and the Variational Principle for Actions of Sofic Groups
Recently Lewis Bowen introduced a notion of entropy for measure-preserving actions of a countable sofic group on a standard probability space admitting a generating partition with finite entropy. By applying an operator algebra perspective we develop a more general approach to sofic entropy which produces both measure and topological dynamical invariants, and we establish the variational princi...
متن کاملCombinatorial Independence and Sofic Entropy
We undertake a local analysis of combinatorial independence as it connects to topological entropy within the framework of actions of sofic groups.
متن کاملDual Entropy in Discrete Groups with Amenable Actions
Let G be a discrete group which admits an amenable action on a compact space and γ ∈ Aut(G) be an automorphism. We define a notion of entropy for γ and denote the invariant by ha(γ). This notion is dual to classical topological entropy in the sense that if G is abelian then ha(γ) = hTop(γ̂) where hTop(γ̂) denotes the topological entropy of the induced automorphism γ̂ of the (compact, abelian) dual...
متن کاملSofic groups and convolution operators
Conjecture: Let Γ be a discrete group, f ∈ L(Γ) and Tf : L (Γ) → L(Γ) be the right convolution by f . Then if Tf is injective, it is surjective as well. We prove the conjecture for the class of sofic groups. AMS Subject Classification: 43A20
