EXTREMAL MATCHING ENERGY OF MOLECULAR GRAPHS WITH GIVEN MATCHING NUMBER TWO
Gutman and Wagner [8] proposed the concept of matching energy and pointed out that the chemical applications of matching energy go back to the 1970s. In this paper, we discuss the matching energies of molecular graphs with given matching number two. In particular, we characterize the graphs with the extremal matching energy in these graphs.
