For and Grothendieck
For Grothendieck topologies, the cohomological properties of a site are invariant of the corresponding category of sheaves of sets viewed abstractly as a topos ( A. Grothendieck ).
The approach of Alexander Grothendieck is concerned with the category-theoretic properties that characterise the categories of finite G-sets for a fixed profinite group G. For example, G might be the group denoted, which is the inverse limit of the cyclic additive groups Z / nZ — or equivalently the completion of the infinite cyclic group Z for the topology of subgroups of finite index.
For example in section 1. 8, Grothendieck proves that a functor is pro-representable if and only if it is left exact.
