Abstract: In this paper, we introduce four new types contractions called in this order Kannan-S-type tricyclic contraction, Chattergea-S-type tricyclic con-traction, Riech-S-type tricyclic contraction, Ciri´c-S-type tricyclic contraction, and we prove the existence and uniqueness for a .fixed point for each situation.
