Book excerpt: The role of Hilbert polynomials in commutative and homological algebra as well as in algebraic geometry and combinatorics is well known. A similar role in differential algebra is played by the differential dimension polynomials. Webthe real polynomials p 1(x);:::;p r(x). The Lebesgue measure in Xwill be denoted by X. The space of real algebraic polynomials on Mof total degree at most t, denoted by P t = P t(M) is the restriction to Mof the space of real polynomials in nvariables. The dimension of the space P t(M) is given by the Hilbert polynomial and it satis es: dimP
