Title: Incomparable Borel linear subspaces of \(\mathbb{R}\) (over \(\mathbb{Q}\))

Abstract: We present a construction of a large family of Borel linear subspaces of \(\mathbb{R}\) (over \(\mathbb{Q}\)), which are incomparable with respect to Borel linear embeddings (over \(\mathbb{Q}\)). A version of this construction answers a question by Frisch and Shinko.
