| Sep 26 at 0:17 | comment | added | TrivialPursuit | Thank you!!! Your answer gives me exactly what I wanted: It is enough that $\pi_{K-x_0}$ has a directional derivative at $u$ in the direction of $z$. Indeed (and this is what I missed, which makes me feel stupid), one has $\pi_{T_n}(z+nu)=\pi_{n(K-x_0)}(z+nu)=n\pi_{K-x_0}(z/n+u)$ which does have a limit as $n\to\infty$ if $\pi_{K-x_0}$ has directional derivatives at $u$. Thank you again! | |
