walking splitting

Notation Split\Split Objects two objects 00 and 11 Morphisms the identities, morphisms i:0→1i : 0 \to 1, p:1→0p : 1 \to 0 satisfying pi=id0pi = \id_0, and the idempotent ip:1→1ip : 1 \to 1. Related Δ≤1\Delta^{\leq 1}, Idem\Idem, Isom\Isom
This category could also be called the "walking split idempotent" (or "walking section", "walking retraction"), but we chose a name that emphasizes that the splitting belongs to the data. Notice that the 55 given morphisms are indeed closed under composition. For example, p∘ip=pp \circ ip = p and ip∘i=iip \circ i = i.The walking splitting can be interpreted as a skeleton of the category of F2\IF_2-vector spaces of dimension ≤1\leq 1.
