A language whose syntactic monoid is nilpotent

Summary: We study the nilpotency of the syntactic monoid of a language. A necessary and sufficient condition for the syntactic monoid of a language to be nilpotent is given and consequently the structure of languages whose syntactic monoid is nilpotent is completely determined.
