For every closed surface, the set of forbidden topological minors is finite.

29 Views Asked by At

I want to prove that for every closed surface, the set of forbidden topological minors is finite.

An idea how to do it is: by starting with the set of forbidden minors. For each forbidden minor $H$, find a finite number of graphs so that every graph with an minor $H$ contains a subdivision of (at least) one of them.

Is there another easier way how to prove it?
