. Let BG be the classifying space of an algebraic group G over the ﬁeld C of complex numbers. We compute a new stable birational invariant deﬁned by the diﬀerence of two coniveau ﬁltrations of a smooth projective approximation of BG × P ∞ .

A cohomology class of a smooth complex variety of dimension \$n\$ has coniveau \$\geq c\$ if it vanishes in the complement of a closed subvariety of codimension \$\geq c\$, and has strong coniveau \$\geq c\$

### Some Spectral Sequences for Filtered Complexes and Applications

Abstract We construct a hierarchy of spectral sequences for a filtered complex under a left-exact functor. As applications we prove (1) the existence of a Leray spectral sequence for de Rham
