Generalisation de la theorie arithmetique des D-modules a la geometrie logarithmique

Abstract : This work aims at generalizing the arithmetic theory of D-modules to logarithmic geometry. We first define sheaves of differentials operators of level m. We describe those sheaves D(m) in local coordinates in the log-smooth case, just as Berthelot did in the non-logarithmic case. Then we study the action of the Frobenius homomorphism on D(m)-modules, and show that F* makes the level raise. Nevertheless, the descent theorem proved by Berthelot for usual schemes is not true in general for log-schemes. Thus we use the work by Lorenzon, which associates a canonical algebra A to a log-scheme, and we get an equivalence of categories between A x D(m) -modules and B x D(0) -modules (indexed). Finally we deduce from this equivalence that the cohomological dimension of D(m) is finite, when X is a smooth scheme over a field, and M is defined by a divisor with normal crossings.
