Aug 25, 2016 at 14:02 comment added Oai Thanh Đào Dear Dr. @darijgrinberg I give a conjecture generalization of Popociviu's inequality as following, and I am looking for a proof. Let $f(x)$ is a real continuous function that is strictly convex on $[m, M]$, let $m \le x_1 \le x_2 \le x_3 \le...\le x_n \le M$ then show that: $nf\left(\frac{x_1+\cdots+x_n}{n}\right)+f(x_1)+\cdots+f(x_n) \ge 2f(\frac{x_1+x_2}{2})+....+2f(\frac{x_{n-1}+x_n}{2})+2f(\frac{x_{n}+x_1}{2}) $ Equality holds if only if $x_1=x_2=\cdots=x_n$

Jun 28, 2015 at 19:26 comment added darij grinberg There are some analogues of Popoviciu's inequality which do have a more interesting structure than just values and their average on the LHS. See artofproblemsolving.com/community/c6h98832p557719
Jun 28, 2015 at 19:24 comment added darij grinberg I fear this is not true. See my post at artofproblemsolving.com/community/c6h244828p1348667
Jun 28, 2015 at 19:16 comment added Joseph O'Rourke It might be worth numerical calculations to verify that it seems to be true...
