The Archimedean property follows immediately from the ordering in the semilattice L, since with this ordering we have f ( x ) \ le f ( y ) if and only if x ^ n = y z for some z and n > 0.

He is noted for many theorems including : H�lder's inequality, the Jordan H�lder theorem, the theorem stating that every linearly ordered group that satisfies an Archimedean property is isomorphic to a subgroup of the additive analysis, including the theories of partial differential equations and function spaces.
