Unformatted text preview: first is the Hodge filtration (1.4.1), (the "bestial" one in the terminology of [8]). The second is the one, noted Z<o and called "canonical" in [8], which is defined by K" if n<p (2.2.2.1) Z<p(K)= Ker(d) if n=p = tO if n>p. The spectral sequence defined by this filtration (2.2.2.2) ~<=.Ef'"=RP+qf.(gr~.K) ~RP+qf,(K) is the d~calage (cf. [8], 1.3.3) of the "second spectral sequence of hyper cohomology" (2.2.2.3) ,,E~ 'q = RP f. (~ffq (K)) => R p +q f.
