چکیده
|
The polyphenyl system is composed of n hexagons obtained from two adjacent hexagons that are sticked by a path with two vertices. the hosoya index of a graph g is defined as the total number of the independent edge sets of g. in this paper,we give a computing formula of hosoya index of a type of polyphenyl system. furthermore,we characterize the extremal hosoya index of the type of polyphenyl system. � 2016 ren shengzhang and wu tingzeng.
