For primes $l\neq p$, $l$-adic cohomology provides a good cohomology theory for varieties over a field of positive characteristic $p$. For $l=p$, there is a whole zoo of $p$-adic cohomology theories. While rigid cohomology provides a well-behaved $p$-adic cohomology theory for all varieties of characteristic $p$, it has the drawback of having only rational coefficients. On the other hand, crystalline cohomology provides a good integral $p$-adic cohomology theory for smooth and proper varieties. In this talk, we explain a joint work with Veronika Ertl and Atsushi Shiho towards the construction of a good integral $p$-adic cohomology theory beyond the smooth and proper case.
