We will difine a base of a smooth fuzzy topological space and investigate some properties of bases. We will prove the existences of initial smooth fuzzy topological spaces. From this fact, we can define subspaces and products of smooth fuzzy topological spaces.

In this paper we shall study the properties of regular relations. We also define syndetically regular relations as the generalizations of syndetical proximalities.
