“Not complicated at all”, at least that is the case I will make. In the deep dark forest prowled by serpentine complexes and monstrous sheaves that are challenging to identify (let alone analyse), rational curves provide a warm and cozy retreat—- the calm of knowing where everything sits and nothing can go wrong. Be it a surface, a threefold, or simply a single curve: if all you care about is what sits near a P1, I will sketch how a little representation theory goes a long way in providing a complete map of the derived category.
