Spectral sequences: opening the black box slowly with an example
For anyone reading this in the distant future: Sean is certainly right to mention the Bockstein spectral sequence. Often those BSSes arising from algebraic situations have differentials which are completely computable. There is a great nest of algebraic examples in Miller--Ravenel--Wilson's famous Periodic phenomena in the Adams--Novikov spectral sequence. |

How nilpotent is the ring of stable homotopy groups of spheres?
At the very least, the proof of Nishida's theorem in II.2.2.9 of Bruner--May--McClure--Steinberger comes with a bound, dependent upon the torsion order of the element x, and there are in turn bounds on the amount of torsion that can appear in a particular degree. May says that Nishida's original proof gives better bounds, and maybe more is known besides those initial things, but definitely bounds are known. |
