Let D be the ring of germs at the origin of linear dierential operators with analytic coefficients. We study minimal free resolutions of D-modules, introduced by M. Granger, T. Oaku and N. Takayama. More precisely we consider modules endowed with a V -filtration along a smooth hypersurface, and the resolutions are adapted to this filtration. We focus on the ranks of such a resolution, which we call Betti numbers, they are invariant for the module considered. First, we give some general results : we reduce the computation of the Betti numbers to a commutative algebra problem, and we dene generic minimal resolutions. Next, we consider a complex hypersurface singularity f = 0 and the module N = D x , t Fs introduced by B. Malgrange, whose rest...
