Subadditivity

English

Etymology

From Template:Prefix.

Noun

1. Template:Lb The state of being subadditive.
2. The statement that a function is subadditive.

   An outer measure ${\mu }^{*}$ satisfies a property called “subadditivity”, viz.: ${\mu }^{*}\left(\bigcup _{j=1}^{\mathrm{\infty }}{A}_j\right)\le \sum _{j=1}^{\mathrm{\infty }}{\mu }^{*}(A_j)$. If the less-than-or-equal sign were replaced with an equal sign then the property would be “additivity” instead.
