For non-constant entire functions f, g: C -> C, say
f '<' g when (Mf)(r) = o( (Mg)(r) ), r in [0, oo),
where for r in [0, oo), (Mf)(r) = max_{|z| = r} |f(z)| and
similarly for r in [0, oo), (Mg)(r) = max_{|z| = r} |g(z)|,
'M' for maximal or maximal function.

If f(z) = z^2 and g(z) = z^3, (Mf) (r) = r^2, (Mg)(r) = r^3, and
for r>0, (Mf) (r) = (1/r)*(Mg)(r) , so (Mf)(r) is o( (Mg)(r) ),
o being little-o notation.

With the '<' strict partial order,
which ordinals can be embedded in (U, '<'), with
U being the set of all entire functions and '<' the
strict partial order defined above?


[ cf. wikipedia for non-crucialness of strict/non-strict:

].
