This work deals with complete residuated lattice-valued nite tree automata (called L-valued tree automata). We investigate the L -valued subautomaton of a tree automaton and also the n-tuple operator consist of n successor is considered and some properties of them are indicated. Also, L bifuzzy topological characterization of L -valued tree automata is considered. Finally, we discuss the homomorphisms between two L -valued tree automata and some theorems are proved
