AbstractLet X be a rigid analytic space and assume that X admits a formal covering inducing on X the structure of a formal scheme. Then, dependent on such a formal structure one associates to X the “reduction”
$$ ilde X$$
which is a scheme of locally finite type over the residue field corresponding to the ground field in question. In this paper the cohomology groups of X are compared with the cohomology groups of
$$ ilde X$$
and a dimension formula is proved. As a consequence it is shown that X is affinoid
$$ ilde X$$
is affine and that an analytic map ϕ:X→Y which is compatible with the formal structures on X and Y is finite if and only if
$$ ilde varphi : ilde X o ilde Y$$
is finite.
