Abstract
What we do here is to define a generalization of Coleman's p-adic integral
(``Torsion points on curves and p-adic abelian integrals'' in
Annals of Math. 121, p. 111-168)
for odd order de Rham classes on a smooth projective
algebraic variety X over a p-adic field K with good reduction V. It
turns out that this theory allows one to associate to each class
a functional on the collection of j
dimensional smooth subvarieties of X having good reduction
![Y\rightarrow \int_Y[\omega ]](img6.gif)
with degrees of freedom given such that the combination
![\sum n_i\int_{Y_i}[\omega ]](img7.gif)
is uniquely defined whenever
is a cycle homologically
equivalent to 0. We also prove a theorem which states that this
last expression can be computed alternatively by interpreting the p-adic
Abel-Jacobi image of the cycle
as a functional on
and evaluating it on
. This
is verified first in the case j=0.
The construction of the integral is performed using two different methods.
One is an extension of the method of Coleman. The other is using a new
cohomology theory, called the finite polynomial cohomology, which is
related to the finite cohomology of Niziol. The basic properties of this
cohomology theory which we prove turn out to be sufficient for proving the
connection with the Abel-Jacobi map.
