Topological Tree Alternative Conjecture for locally finite trees
Let be a locally finite tree, and write when and are mutually topological minors, meaning and . Count the isomorphism classes of such trees .
Topological Tree Alternative Conjecture. For a given locally finite tree , the number of isomorphism classes of trees that are mutually topological minors with is either or .
This is the topological-minor analogue of the Tree Alternative Conjecture. It gives a sharp alternative for the size of each mutual-topological-minor equivalence class, and the supplied text does not state that it has been resolved.
