Item New bounds for Randic and GA indices(Springer, 2013) Lokesha, V.; Shetty, B. Shwetha; Ranjini, P. S.; Çevik, Ahmet Sinan; Cangül, İsmail Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Anabilim Dalı.; 0000-0002-0700-5774; 0000-0002-0700-5774; ABA-6206-2020; J-3505-2017; 57189022403The main goal of this paper is to present some new lower and upper bounds for the Randic and GA indices in terms of Zagreb and modified Zagreb indices.Publication On certain topological indices of the derived graphs of subdivision graphs(Turkic World Mathematical Soc, 2016-01-01) Hosamani, S. M.; Lokesha, V.; Devendraiah, K. M.; Cangül, İsmail Naci; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Matematik Bölümü.; 0000-0003-2468-9511; 0000-0002-0700-5774; J-3505-2017; ABA-6206-2020The derived graph [G]dagger of a graph G is the graph having the same vertex set as G, with two vertices of [G]dagger being adjacent if and only if their distance in G is two. Topological indices are valuable in the study of QSAR/QSPR. There are numerous applications of graph theory in the field of structural chemistry. In this paper, we compute generalized Randic, general Zagreb, general sum-connectivity, ABC, GA, ABC(4), and G Lambda(5) indices of the derived graphs of subdivision graphs.Item On the Zagreb indices of the line graphs of the subdivision graphs(Elsevier Science, 2011-01-01) Ranjini, P. S.; Lokesha, V.; Cangül, İsmail Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü.; 0000-0002-0700-5774; ABA-6206-2020; 57189022403The aim of this paper is to investigate the Zagreb indices of the line graphs of the tadpole graphs, wheel graphs and ladder graphs using the subdivision concepts.Item Zagreb polynomials of three graph operators(Univ Nis, 2015-06-20) Bindusree, A. R.; Lokesha, V.; Çevik, A. Sinan; Cangül, İsmail Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü.; 0000-0002-0700-5774; J-3505-2017; ABA-6206-2020; 57189022403In general, the relations among Zagreb polynomials on three graph operators are discussed in this paper. Specifically, relations between Zagreb polynomials of a graph G and a graph obtained by applying the operators S(G), R(G) and Q(G) are investigated. In a separate section, the relation between Zagreb polynomial of a graph G and its corona is also described.
