Classification of smooth algebraic surfaces with a smooth morphism to $\Bbb P^1$
Thanks, the tool of moduli space is wonderful. Last but not least, what about the case $g=0$?

Hi, do you find some good references now?

mod p etale cohomology of the special fiber and the generic fiber
While the argument is clever, and you get that the special fiber's etale cohomology can be controlled by the de Rham cohomology in special fiber, buy how do you control the latter term by the etale cohomology of the generic fiber? (BMS is for the opposite direction)

@R.vanDobbendeBruyn By a semilinear lemma 0A3L the Artin-Schreier long exact sequence splits, see stacks.math.columbia.edu/tag/0A3J
