Oct 2, 2019 at 15:23 comment added Manuel @user100927 Thanks! In Thm 3.5.4 I am having trouble to understand the identity used for $\frac{d^l}{\partial x^l}I_R(u-p)(x)$. But i assume it would be easier in my setting. If $p$ is the taylor expansion in $x$ of $f$ what would $(\pi(f - p))^r$ be?. I understand $f-p$ is an $2m$ times diferentiable in $x$ such that $| f(y)-p (y)| \leq \|f^{(2m)}\|_\infty(x-y)^{(2m)}$.
Oct 2, 2019 at 14:03 comment added user100927 you can prove exactness for polynomials and then it follows see for instance Thm 3.5.4 (page 73) here: research-collection.ethz.ch/bitstream/handle/20.500.11850/…
