Resumo:
The talk will outline basic constructions and properties of cellular approximation, mostly in homological algebra, and group theory. Cellular approximation attempts to examine spaces or groups by constructing "approximations" using a chosen group or space such as the spheres or a given finite group, or a give chain complex. Thus taking the subgroup generated by torsion elements is an example. So are canonical central extensions and the usual (spherical) CW-approximation.
