Coatoms of the lattice of funcoids

Author(s): Porton

\begin{problem} Let $A$ and $B$ be infinite sets. Characterize the set of all coatoms of the lattice $\mathsf{FCD}(A;B)$ of funcoids from $A$ to $B$. Particularly, is this set empty? Is $\mathsf{FCD}(A;B)$ a coatomic lattice? coatomistic lattice? \end{problem}

Keywords: atoms; coatoms; funcoids
