Talk:Aufgaben:Problem 15

--Brynerm (talk) 11:38, 11 June 2015 (CEST) Just a remark. Wikipedia says \(T(\phi)\) continous \( \Leftrightarrow \exists k\in \mathbb{N}_0 \;|T(\phi)| \leq C \|\phi\|_{C_b^k(K)} := C \sum_{|\alpha| \leq k}^{} \sup_{x \in K}\left| \partial^\alpha \phi(x) \right|\)

That would probably relay more on part a) than your solution, but what you did, looks fine too to me.

--yzemp (talk) 14:19, 11 June 2015 (CEST) Yeah, we were aware of this definition, the problem is that we can't rely on wikipedia definitions when we solve these tasks. We found it better to stick to the script, this way we can be sure that we are allowed to use the definitions.
