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.
