When is “independence of l” known?
For the individual cohomology groups $H^i$, then no. |

But what you can deduce is $\ell$-independence for the alternating sums of traces. |

When is “independence of l” known?
Ah, actually reflecting on it a bit more, I think I got a bit carried away. What I was thinking was that if the weight-monodromy conjecture were true, then to know $\ell$-independence, you need to know $\ell$-independence of traces for everything appearing in the $E_2$ page of the weight spectral sequence (since these are then the graded pieces of the monodromy filtration). Now although you know independence of everything on the $E_1$ page, this doesn't imply $\ell$-independence for everything on the $E_2$ page (this was the mistake I made). |

The topology on the Robba ring
Yes, I wondered about that but I don't think so. There will be elements of $\mathcal{R}_K$ for which that norm is not defined for any $r$, since we require convergence on some semi-open annulus $p^{-r}\leq t <1$ rather than the closed annulus $p^{-r}\leq t\leq 1$. |
