Algebraists like decompositions, for doing parallel computing, etc. Some decompositions are very "successful", some others are not. We try to find the "reasons of sucess" by looking at various instants, including decompositions of semisimple rings. We also get "Generalized Discrete Fourier Transforms" for group rings and related structures. Finally, we try to solve equations of degree >4.

This is joint work with Manuel Kauers.

Which (sub)direct decompositions are "useful"?

This talk will describe some of the history and background of one of the oldest (now solved) problems in algebraic topology.
