Flows Associated with Ergodic Non-Singular Transformation Groups
Flows Associated with Ergodic Non-Singular Transformation Groups
In this paper we shall give a nice invariant for the weak equivalence of ergodic non-singular transformation groups.It is a one-parameter ergodic non-singular flow associated with an ergodic non-singular transformation group.Since in 1960 an example of an ergodic non-singular transformation without <r-finite invariant measures was given in Ergodic theory [16], …
