A NOTE ON BITRANSFORMATION GROUPS

We study some dynamical properties in the context of bitransformation groups, and show that if (H,X,T) is a bitransformation group such that (H,X) is almost periodic and (X/H,T) is pointwise almost periodic and , then is a compact topological group and when H is abelian, where E(H,X) is the enveloping semigroup of the transformation group (H,X).
