Abstract

We point out incorrect lemmas in some papers regarding the C-algebras associated with subshifts written by the second named author. To recover the incorrect lemmas and the affected main results, we will describe an alternative construction of C-algebras associated with subshifts. The resulting C-algebras are generally different from the originally constructed C-algebras associated with subshifts and they fit the mentioned papers including the incorrect results. The simplicity conditions and the K-theory formulae for the originally constructed C-algebras are described. We also introduce a condition called () for subshifts such that under this condition the new C-algebras and the original C-algebras are canonically isomorphic to each other. We finally present a subshift for which the two kinds of algebras have different K-theory groups.
