Abstract

The Zagreb indices have been introduced in 1972 to explain some properties of chemical
compounds at molecular level mathematically. In this paper we define first modified Zagreb
index, second modified Zagreb index, first Zagreb complexity index and second Zagreb
complexity index for degree based vertex labeled graphs. We also compute degree based vertex
labeled Zagreb indices for some standard graphs and some chemical signed graphs.
