Talk:Additive Function is Strongly Additive

When the codomain is $\overline{\R}$, subtraction is tricky business; the page needs rephrasing to avoid minus signs. --Lord_Farin 11:59, 16 March 2012 (EDT)


 * What is proven is $f\left({A}\right) + f\left({B}\right) = f\left({A \cup B}\right) + f\left({A \cap B}\right)$. How about changing it to that? Abcxyz 12:22, 16 March 2012 (EDT)


 * That particular statement is called that '$f$ is strongly additive'; I put it up a sec ago for measures: Measure is Strongly Additive. So I suggest this page to be rephrased and moved to Additive Function is Strongly Additive. Anyone disagree? --Lord_Farin 12:30, 16 March 2012 (EDT)


 * I think that's a good idea. Anyway, maybe we should have a definition page for a strongly additive function? Abcxyz 12:38, 16 March 2012 (EDT)

Yes, haven't gotten round to writing it, but there's a link already on Measure is Strongly Additive. --Lord_Farin 15:29, 16 March 2012 (EDT)
