We study the slopes of Frobenius on the rigid cohomology and the rigid cohomology with compact support of an algebraic variety over a perfect field of positive characteristic. We then prove that any unipotent overconvergentF-isocrystal on a smooth variety has a slope filtration whose graded parts are pure.
