Abstract
In this note we derive for a smooth projective variety with normal crossing divisor an integral comparison between the log-crystalline cohomology of the associated log-scheme and the logarithmic overconvergent de Rham–Witt cohomology defined by Matsuue. This extends our previous result that in the absence of a divisor the crystalline cohomology and overconvergent de Rham–Witt cohomology are canonically isomorphic.
