For every proximity exists, does there exist a uniformity which generates this proximity?

For every proximity exists, does there exist a uniformity which generates this proximity?

This question may be generalized for different kinds of generalizationgeneralizations of proximities and uniformities. In fact I need it for funcoids and reloids: Does for every funcoid f exists$f$ does there exist a reloid g$g$ which generates it (that is f = (FCD)g$f = (\operatorname{FCD})g$)?

Reloids are just filters on the set of binary relations (on some set).

Funcoids are essentially a generalization of proximities with only the following axioms:

  • ¬(∅ δ X) and ¬(X δ ∅);
  • (A∪B)δC ⇔ AδC ∨ BδC;
  • Cδ(A∪B) ⇔ CδA ∨ CδB.
