This second volume contains chapters 3 and 4 of the author's study of the functoriality of the stable homotopy categories of schemes. In the previous volume, he concentrated on the six operations \(f^*\), \(f_*\), \(f_!\), \(f^!\), \(-\otimes -\) and \(\underline{\mathbf {Hom}} (-,-)\), their constructibility and exactness.

This volume begins with the construction of the nearby motive functors \(\Psi _f\) which are the analogue of the nearby cycles functors, well-known in étale cohomology. The author then extends the vanishing cycles formalism to these functors. In particular, he computes the effect of the functor \(\Psi _f\) in the case where \(f\) has semi-stable reduction. He also shows that \(\Psi _f\) preserves constructible motives and commutes with external tensor product and duality. He then defines a monodromy operator and proves that this operator is nilpotent.

The last chapter, which is of a different nature than the previous ones, recalls in full detail the construction of the stable homotopy category of \(S\)-schemes.
