The Lattice of Functional Alexandroff Topologies

Order, 2020
Let \(X\) be a set and \(f:X \longrightarrow X\) be a function; then \(\mathcal{P}(f):=\{O \subseteq X: f^{-1}(O)\subseteq O\}\) is an Alexandroff topology on \(X\). A space \((X, \mathcal{T})\) is said to be primal [\textit{O. Echi}, Topology Appl. 159, No. 9, 2357--2366 (2012; Zbl 1245.54033)], or functional Alexandroff [\textit{F. A. Z. Shirazi} and
