- The Adams spectral sequence was invented as a tool for computing stable homo-topy groups of spheres, and more generally the stable homotopy groups of any space.
- There are two Eilenberg-Moore spectral sequences that we shall consider, one for homology and the other for cohomology. In contrast with the situation for the
