Abstract.

It is shown that the class of all non-separable extensions of a nonzero σ-finite Borel measure in the topological vector space , which are invariant under some everywhere dense continual subgroup of and which possess the uniqueness property, has maximal cardinality 22c. Some related questions concerning the measurability properties of real-valued functions with respect to the class of non-separable measures are also discussed.
