Semistable reduction and log structures
Ah that's actually really useful. I guess I had just naively assumed that you could glue the above log structure to get something on the whole of $X_k$, but clearly this was a mistake. |

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). |
