Foundational Papers

Author & Title File

Serre - Homologie Singuliere des Espaces Fibres

This paper is Serre's Annals exposition of his eponymous spectral sequence and the basic properties.


Steenrod, Thomas - Cohomology Operations derived from Cyclic Groups

The paper provides an analysis of the Steenrod squares and reduced power operations.


Milnor - The Steenrod Algebra and its Dual

This beautiful paper describes the Hopf algebra structure of the Steenrod algebra and the dual Steenrod algebra.


Serre - Cohomology modulo 2 des complexes d'Eilenberg-MacLane

This is Serre's computation of the cohomology of Eilenberg-MacLane spaces.


Serre - Groupes d'homotopie et classes de groupes abeliens

This is an introduction to Serre classes and computations of homotopy groups using them.


Adams - On the Structure and Applications of the Steenrod Algebra

Adams' construction of the Adams spectral sequence and an exposition of some of its basic properties.


May - The Cohomology of the Steenrod Algebra

This is an unpublished book by May describing the May spectral sequence and computations therewith.


Adams - On the Non-Existence of Elements of Hopf Invariant One

This is Adams' original proof of the non-existence of Hopf invariant one elements beyond dimension 7. He explicitly decomposes the primary operations into secondary ones!


Liulevicius - The Factorization of Cyclic Reduced Powers by Secondary Cohomology Operations

This is the odd primary analogue of Adams' Hopf Invariant One paper.


Bruner, McClure, May, Steinberg - $H_\infty$-Ring Spectra and their Applications

This book is a detailed and complete analysis of spectra with power operations and their relations with such things as the Adams spectral sequence.


Eilenberg, Moore - Homology and Fibrations 1

This paper establishes the basics of the Eilenberg-Moore spectral sequence and the functor Cotor.



Serre Spectral Sequence for Loops S^3 The Serre Spectral Sequence for Loops S^3.
Serre Spectral Sequence for U(3) The Serre Spectral Sequence for U(3). Circled classes are algebra generators.
Serre Spectral Sequence for V2R5 The Serre Spectral Sequence for 2-frames in R5. The drawn differential is multiplication by 2.
Serre Spectral Sequence for V2R6 The Serre Spectral Sequence for 2-frames in R6.
