We also study the maps n and qn providing explicitdescription of their kernels. Finally, we implement an algorithm which leads to the computation of thesekernels. %K Fontaine sheaves %K p-adic cohomology %K crystalline cohomology. %U http://journals.aulonapress.com/index.php/ajm/article/view/255/345
