A Counterexample for Lightning Flash Modules over E(e1,e2)
arXiv:1507.01039 · doi:10.1007/s00013-016-0880-8
Abstract
We give a counterexample to Theorem 5 in Section 18.2 of Margolis' book, "Spectra and the Steenrod Algebra", and make remarks about the proofs of some later theorems in the book that depend on it. The counterexample is a module which does not split as a sum of lightning flash modules and free modules.
