Nodal geometry of graphs on surfaces
Yong Lin, Gabor Lippner, Dan Mangoubi +1
We prove two mixed versions of the Discrete Nodal Theorem of Davies et. al. [3] for bounded degree graphs, and for three-connected graphs of fixed genus . Using this we can show…

Ricci-flat graphs with girth at least five
Yong Lin, Linyuan Lu, S. -T. Yau
A graph is called Ricci-flat if its Ricci-curvatures vanish on all edges. Here we use the definition of Ricci-cruvature on graphs given in [Lin-Lu-Yau, Tohoku Math., 2011], which i…
