Jones' conjecture for Halin graphs and a bit more
arxiv(2024)
摘要
We prove Jones' famous conjecture for Halin graphs and a somewhat more
general class of graphs too. A based planar graph is a planar one that has a
face adjacent to every other face. We confirm Jones' conjecture for based
planar graphs. Namely, if a based planar graph does not contain k+1
vertex-disjoint cycles, then it suffices to delete 2k vertices to make it
acyclic.
