Abstract: During the execution of functional logic programs, E-unification problems have to be solved quite frequently, where the underlying equational theory is induced by recursive functions. But, what about the decidability of those E-unification problems? Up to now, there does not exist a concrete answer to this question for classes of equational theories which are induced by particular recursive functions. In this paper, we try to give an answer to this question by drawing and verifying a strict... (Update)
