We construct an integral
-adic
cohomology that compares with rigid cohomology after inverting
. Our approach is
based on the log-Witt differentials of Hyodo–Kato and log-étale motives of Binda–Park–Østvær.
In case
satisfies resolution of singularities, we moreover prove that it agrees with the “good” integral
-adic
cohomology of Ertl–Shiho–Sprang; from this we deduce some
interesting motivic properties and a Künneth formula for the
-adic
cohomology of Ertl–Shiho–Sprang.
