摘要
通过图变换,给出当单圈图的圈长为偶数时其Mostar指标和加权Mostar指标的下界,并刻画达到下界的极值图.
By using graph transformation,we give the lower bounds for the Mostar index and the weighted Mostar index of unicyclic graphs when the cycle length of unicyclic graphs is even,and characterize the extremal graphs that achieve the lower bounds.
