1. The problem statement, all variables and given/known data
Let's consider a distribution function $f=f(t,x^i,E,p^i)$. Is it true that
$\mathop {\lim }\limits_{p \to\infty}p^{\alpha}f=0$ $\forall\alpha\in R$?

2. Relevant equations

3. The attempt at a solution
I think so, not sure though. Thanks in advance!
