Adjunctions and limits

A left adjoint preserves colimits (CategoryTheory.Adjunction.leftAdjointPreservesColimits), and a right adjoint preserves limits (CategoryTheory.Adjunction.rightAdjointPreservesLimits).

Equivalences create and reflect (co)limits. (CategoryTheory.Adjunction.isEquivalenceCreatesLimits, CategoryTheory.Adjunction.isEquivalenceCreatesColimits, CategoryTheory.Adjunction.isEquivalenceReflectsLimits, CategoryTheory.Adjunction.isEquivalenceReflectsColimits,)

In CategoryTheory.Adjunction.coconesIso we show that when F ⊣ G, the functor associating to each Y the cocones over K ⋙ F with cone point Y is naturally isomorphic to the functor associating to each Y the cocones over K with cone point G.obj Y.
