چکیده
|
The concept of geometricarithmetic indices (ga) was put forward in chemical graph theory very recently. in spite of this, several works have already appeared dealing with these indices. in this paper we present lower and upper bounds on the second geometricarithmetic index (ga2) and characterize the extremal graphs. moreover, we establish nordhaus-gaddum-type results for ga2
