Borel G-space

A (standard) Borel G-space is defined in connection with a standard Borel space which needs to be specified first.

Basic definitions

Remark 0.1   Borel G-spaces have the nice property that the product and sum of a countable sequence of Borel G-spaces $ (X_n)_{n \in N}$ are also Borel G-spaces. Furthermore, the subspace of a Borel G-space determined by an invariant Borel set is also a Borel G-space.
