Cycle Bases Structure of out Planar Graphs on the Projective Plane in Mechanics Engineering
Mei Hua Xu · Applied Mechanics and Materials · 2013
In this paper we investigate the cycle base structure of 2-connected graphs on the projective plane and show the minimum cycle bases of 2-connected outer planar graph G in the case of ew (G) 5. Then give a proof about the one-one property between the minimum cycle bases and the shortest no contractible cycles.
