We define a power structure over these (semi)rings. This means that, for a power series A(t)=1+∑i=1∞[Ai]ti with the coefficients [Ai] from R and for [M]∈R, there is defined a series (A(t))[M], also with coefficients from R, so that all the usual properties of the exponential function hold. In the particular case A(t)=(1−t)−1, the series (A(t))[M] is the motivic zeta function introduced by M. Kapranov. As an application we express the generating function of the Hilbert scheme of points, 0-dimensional subschemes, on a surface as an exponential of the surface.engA power structure over the Grothendieck ring of varietiesjournal articlehttp://intlpress.com/site/pub/pages/journals/items/mrl/content/vols/0011/0001/a006/index.htmlhttp://www.intlpress.com/restricted access511Algebraic-VarietiesSpacesGeometryTeoría de números1205 Teoría de Números
