The first gap for total curvatures of planar graphs with nonnegative curvature
Bobo Hua, Yanhui Su
We prove that the total curvature of a planar graph with nonnegative combinatorial curvature is at least if it is positive. Moreover, we classify the metric structur…

Infinitely many excluded minors for frame matroids and for lifted-graphic matroids
Rong Chen, Jim Geelen
We present infinite sequences of excluded minors for both the class of lifted-graphic matroids and the class of frame matroids.
