摘要
Abstract
By using some transforms of graphs,the graphs simultaneously minimizing all Lapla cian coefficients ck were determined among all cacti graphs with given order, cycle number and matching number. Also,the graphs simultaneously minimizing all Laplacian coefficients o were characterized among all cacti graphs with fixed order and cycle numbe. Moreove.some graphs with extremal Laplacian-like energy were identified among all cacti graphs.关键词
