| May 20, 2020 at 0:02 | comment | added | Wlod AA | YCor, "...admits a structur of $\Bbb{Z}[\frac1{2}]$-module ..." -- not quite (if I understand you properly). Cancellation property (etc.) allows for something like "convex sets". My full theorem from the past actually stated that each such structure is uniquely embedded (up to an isomorphism) in a whole weirdo which is generated by this structure. (it's like embedding a convex set in proper linear space). #### BTW, term "weirdo" I have invented only a few days ago. | |
