La vista des de l’hotel
The poster depicts a factorisation. At the top we find a mapping f, from A to B, represented by the work of picking vegetables from the field and depositing them in the warehouse. It decomposes into three mappings, a surjective one (left), the projection from A to A/Ker(f), given by the partition of the vegetables according to their storage place; a bijective one (bottom), from A/Ker(f) to Im(f), given by the deposit of the piles in the corresponding boxes; and an injective one (right), the inclusion from Im(f) to B, given by the movement of the boxes to its destination. The farmer is the mathematician Emmy Noether, author of this theorem and a fundamental figure of modern day algebra.
