Sorry for the long title. What I mean is that for two vectors (a_1,...,a_n) and (b_1,...,b_n) with the property $a_i,b_i \geq 0 $ and $ \sum a_i =\sum b_i =1$.
If $ -\sum a_ilog(a_i) > -\sum a_ilog(a_i) $$ -\sum a_ilog(a_i) > -\sum b_ilog(b_i) $ implies $\sum a_i^2 < \sum b_i^2$ or something similar?
