Abstract
A C*-symbolic dynamical system
(A, ρ, Σ)
is a finite family
{ρα}α ∈Σ
of endomorphisms of a C*-algebra A
with some conditions.
It yields a C*-algebra Oρ
from an associated
Hilbert C*-bimodule.
In this paper, we will extend the notion of
C*-symbolic dynamical system to
C*-textile dynamical system
(A, ρ, η, {Σρ}, {Ση}, κ)
which consists of two
C*-symbolic dynamical systems
(A, ρ, {Σρ})
and
(A, η, {Ση})
with certain commutation relations
κ
between their endomorphisms
{ρα}α ∈ Σρ
and
{ηa}a ∈ Ση.
C*-textile dynamical systems yield two-dimensional subshifts and
C*-algebras Oκρ,η.
We will study their structure of the algebras
Oκρ,η
and present its K-theory formulae.
