A dichotomy for Polish modules
@article{Frisch2020ADF, title={A dichotomy for Polish modules}, author={Joshua Frisch and Forte Shinko}, journal={arXiv: Logic}, year={2020} }
Let $R$ be a ring equipped with a proper norm. We show that under suitable conditions on $R$, there is a natural basis under continuous linear injection for the set of Polish $R$-modules which are not countably generated. When $R$ is a division ring, this basis can be taken to be a singleton.

It is shown that there is a homomorphism reducible to L of the countable power of the group of increasing homeomorphisms of the unit interval such that every every Kσ subgroup of G^\omega $$Gω is homomorphicism reduces to L.
