Endomorphisms of words in a quiver
We extend the classical concept of a word in an alphabet to that of a word in a quiver. Then the endomorphisms for such a word are introduced. They form a monoid which provides some information about recurrence and periodicity of the fixed word. The properties of this monoid are used to show that for a typical class of indecomposable modules over a finite dimensional algebras of tame representation type, the class of their endomorphism rings is a very restricted one.
