Growing Spines: Ad Infinitum et Ad Infinitesimalia

Blaise Boissonneau, Anna De Mase, Franziska Jahnke +1

We prove that for every ordered abelian group $G$ there exists a non-trivial ordered abelian group $H$ such that $G ≼ H \oplus G$ with the lexicographic order, and give a…

Growing Spines Ad Infinitum

Blaise Boissonneau, Anna De Mase, Franziska Jahnke +1

We show that every non-trivial ordered abelian group $G$ is augmentable by infinite elements, i.e., we have $G ≼ H \oplus G$ for some non-trivial ordered abelian group $H$ …
