Multiplicative structure on spectral sequence

As far as I know that 1954 paper of Massey is faulty, and you cannot get multiplicative spectral sequences just from such stucture on an exact couple. The best I know that you can do is to use Cartan- …

Strong convergence of whole-plane spectral sequences

The spectral sequences $E^\alpha$ and $E^\beta$ arise from two different filtrations of $C$, which have different completions, say $\widehat C^\alpha$ and $\widehat C^\beta$. The first converges stro …

Multiplicativity of the homology Atiyah-Hirzebruch spectral sequence for a ring spectrum

(A comment to Tyler's answer.) Strictifying pairings from the stable homotopy category to spectra can be tricky. To even get started with an inductive approach let me assume $E$ is connective, so th …

Conditionally convergent spectral sequences with exiting and entering differentials

After a long life in preprint form, Boardman's paper was published in the conference proceedings celebrating his 60th birthday: \bib{MR1718076}{article}{ author={Boardman, J. Michael}, …

Does a filtered A_N algebra give rise to a multiplicative spectral sequence?

For the $d_r$-differentials to be derivations, i.e., to satisfy the Leibniz rule $d_r(x \cdot y) = d_r(x) \cdot y \pm x \cdot d_r(y)$ with $x \cdot y = m_2(x \otimes y)$, it is enough to have a filter …

Third differential in the homology AHSS

The realification map $BU \to BSO$ lifts through $BSpin^c$, because the first Chern class provides an integral lift of the second Stiefel-Whitney class. Calculating with the Serre spectral sequence f …

The Hochschild–Serre spectral sequence and cup products

The original reference is Hochschild, G.; Serre, J.-P. Cohomology of group extensions. Trans. Amer. Math. Soc. 74 (1953), 110–134. On page 118 they introduce a filtration $\{A_j\}_j$ of the cochain c …

$BP$-Adams Novikov Spectral Sequence or Homotopy groups of $S/3$

For $3$-primary homotopy of $S$ there is early work by Nakamura, Osamu Some differentials in the mod 3 Adams spectral sequence. Bull. Sci. Engrg. Div. Univ. Ryukyus Math. Natur. Sci. No. 19 (1975), 1– …

How to compute the cohomology of the general linear group with integral entries

There are homological stability results (due to Ruth Charney and Hendrik Maazen around 1979, if I recall correctly) saying that $H_*(GL_n(Z); Z) \to H_*(GL_{n+1}(Z); Z)$ is about $n/2$-connected. So …

Some examples with one nonzero family of differentials: The classical Adams spectral sequence for $j/p$, the connective image-of-J spectrum reduced mod $p$, collapses at $E_3$, by Theorems 4.5 (at $p= …

Differentials in the Adams Spectral Sequence for spheres at the prime p=2

With the aid of machine computations, you can readily determine the Adams differentials up to $t-s=30$ using the multiplicative structure, the relation between Steenrod operations in $\text{Ext}_A$ an …

Spectral sequences and short exact sequences

Loop-space functor on cohomology
