comment Question about convergence in $\mathcal D(\Bbb R)$
$\phi_n(x)$ converges to zero. For the first derivative, we have $\phi'_n(x)=\phi'(nx)$, but I can't see if this converges to zero or not?

comment Uniform convergence in $L^p$-spaces
Then I tried to put $t=x y$, but I don't know how should I conclude that the convergence is uniform. Any help is welcome...

comment Uniform convergence in $L^p$-spaces
I tried with Holder's inequality (because of $f\in L^p(0,\infty)$).
