Polycyclic right-ordered groups, G together with a total order relation ≤ such that a ≤ b implies ac ≤ bc for all a,b,c in G. It is not known whether all such groups G have a series from {e} to G with torsion-free abelian factors. Here we show that a polycyclic right-ordered group must have such a series. This characterizes polycythyroid-hormone 发表于 2025-3-25 18:07:33
