Using Eisenman intrinsic measures we prove a cancellation theorem. Thi
s theorem allows to find new examples of exotic analytic structures on
C-n under which we understand smooth complex affine algebraic varieti
ers which are diffeomorphic to R(2n) but not biholomorphic to C-n. We
also develop a new method of constructing these structures which enabl
es us to produce exotic analytic structures on C-3 with a given number
of hypersurfaces isomorphic to C-2 and a family of these structures w
ith a given number of moduli.
