A necessary and sufficient condition that ![[alpha^']](/images/equations/MuirheadsTheorem/Inline1.svg)

for all positive values
of the

, then
![[alpha^']<=[alpha],](/images/equations/MuirheadsTheorem/NumberedEquation1.svg) |
with equality only when (
) and (

are equal. See Hardy et al. (1988) for a definition
of notation.
