A note on 1-planar graphs with minimum degree 7

Published 3 Oct 2019 in math.CO and cs.DM | (1910.01683v1)

Abstract: It is well-known that 1-planar graphs have minimum degree at most 7, and not hard to see that some 1-planar graphs have minimum degree exactly 7. In this note we show that any such 1-planar graph has at least 24 vertices, and this is tight.
