(joint work in progress with F. Andreatta and A. Vezzani) We introduce a definition of relative Hyodo-Kato cohomology for rigid analytic varieties, based on the relative motivic nearby cycle functor, and a corresponding theory of coefficients. We prove a Hyodo-Kato isomorphism with de Rham cohomology, provide an explicit description of the « constructible » objects, and compare this definition to relative log-rigid cohomology.
