Abstract
We consider the simplicity of the -algebra associated to an arbitrary weakly left-resolving labeled space , where is the smallest nondegenerate accommodating set. We classify all gauge-invariant ideals of and characterize minimality of in terms of ideal structure of . Using these results, we prove that is simple if and only if is strongly cofinal and satisfies condition , and for any and , there is such that , and if and only if is minimal and satisfies condition , and if and only if is minimal and satisfies condition .
