- Algebras Generated by Partial Isometries
We associate to each discrete partial dynamical system a universal C-algebra generated by partial isometries satisfying relations given by a Boolean algebra connected to the discrete partial dynamical system in question. We show that for symbolic dynamical systems like one-sided and two-sided shift spaces and topological Markov chains with an arbitrary state space the C-algebras usually associa...
متن کاملD ec 1 99 7 PARTIAL DYNAMICAL SYSTEMS AND C ∗ - ALGEBRAS GENERATED BY PARTIAL ISOMETRIES
A collection of partial isometries whose range and initial projections satisfy a specified set of conditions often gives rise to a partial representation of a group. The Calgebra generated by the partial isometries is thus a quotient of the universal C-algebra for partial representations of the group, from which it inherits a crossed product structure, of an abelian C-algebra by a partial actio...
متن کاملWeak C-Hopf Algebras and Multiplicative Isometries
We show how the data of a finite dimensional weak C∗-Hopf algebra can be encoded into a pair (H, V ) where H is a finite dimensional Hilbert space and V :H⊗H → H⊗H is a partial isometry satisfying, among others, the pentagon equation. In case of V being unitary we recover the Baaj-Skandalis multiplicative unitary of the discrete compact type. Relation to the pseudomultiplicative unitary approac...
متن کاملExtensions of Boolean isometries
We study when a map between two subsets of a Boolean domain W can be extended to an automorphism of W . Under many hypotheses, if the underlying Boolean algebra is complete or if the sets are finite or Boolean domains, the necessary and sufficient condition is that it preserves the Boolean distance between every couple of points.

and Applied Analysis 3 The left multiplication by a ∈ A is the mapping La : A → A, which is defined as La x ax for all x ∈ A. Observe that, for a, b ∈ A, Lab LaLb and that La Lb implies a b. If a ∈ A is both Moore-Penrose and group invertible, then La† La † and La# La # in the Banach algebraL A . According to 4, Remark 12 , a necessary and sufficient condition for a ∈ A to be EP is that La ∈ L ...
