Abstract

The Khovanskii finiteness theorem calculates an upper bound for the number of connected components of the intersection of an algebraic set with a Pfaff manifold in R^n. This paper uses the algebraic methods of Wu Wen-tsun to give an elementary pioof of Khovanskii's theorem. An extension of the Wu-Ritt zero structure theorem is also obtained.
