| Abstract: | A fixed-double bond is an edge which is in all perfect matching of a hexagonalsystem, This paper considered fixed-double bonds of hexagonal systems. Weobtained a necessary and sufficient condition of hexagonal systems which have fixeddouble bonds by introducing the concept of second generalized cut segment. |
