    Created a new page on right-connected double categories, with a basic definition and reference. I intend to fill in with more details and examples soon.

    I have changed

    “identity map” to “identity-assigning map”


    “codomain map” to “codomain-assigning map”.

    Also added

    hyperlink to “right adjoint

    Added the “main theorem” which characterises those right-connected double categories which arise from algebraic weak factorisation systems. Also fixed some examples.

    Added several more examples, and two more basic properties: one characterising the thin right-connected double categories, and the other concerning orthogonal factorisation systems.
