| Aug 3, 2015 at 13:42 | comment | added | James | This works, thank you. I am looking for a reference including the proof for weighted graphs, to cite it in a paper. The closest one that I could find is 'Algebraic graph theory' by R. Royle, Springer 2001, but it includes the proof for non-weighted graphs only. Do you know a reference containing the proof in the weighted case? | |
