A new theorem and a conjecture

I’ve just proved the following:

Theorem (\mathsf{FCD}) (\mathsf{RLD})_{\Gamma} f = f for every funcoid f.

For a proof see this online article.

I’ve also posed the conjecture:

Conjecture (\mathsf{FCD}) : \mathsf{RLD} (A ; B) \rightarrow \mathsf{FCD} (A ; B) is the upper adjoint of (\mathsf{RLD})_{\Gamma} : \mathsf{FCD} (A ; B) \rightarrow \mathsf{RLD} (A ; B) for every sets A, B.

    I have also proved that (\mathsf{RLD})_{\Gamma} is neither upper nor lower adjoint of (\mathsf{FCD}) (see the same online article above).
