A generalization of Coleman’s p-adic integration theory

We associate to a scheme X smooth over a p-adic ring a kind of cohomology group H ⁱ _fp (X,j). For proper X this cohomology has Poincaré duality hence Gysin maps and cycle class maps which are reasonably explicit. For zero-cycles we show that the cycle class map is given by Coleman integration. The cohomology theory H _fp is therefore interpreted as giving a generalization of Coleman’s theory. We find an embedding H _syn ²ⁱ (X,i)↪H _fp ²ⁱ (X,i) where H _syn is (rigid) syntomic cohomology. Our main result is an explicit description of the syntomic Abel-Jacobi map in terms of generalized Coleman integration.
