چکیده
|
the first general multiplicative zagreb index p_1^a(g) is the product of the degree of each vertex v in g, raised to the power a and the second general multiplicative zagreb index p_2^a(g) is the product of the degree of each vertex v in g, raised to the power a times the degree of v, where a is a non-zero real number.in this study, we present bounds on the general multiplicative zagreb indices for trees and unicyclic graphs. we also provide bounds for the first general multiplicative zagreb index for trees.additionally, we identify all the extremal graphs for each bound mentioned as best as possible.
