Item Degree Based Topological Co-Indices of Graphs(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Muhammad Nasir; SP19-RMT-032; LHR TP 6481; Dr. Muhammad Kamran SiddiquiGraph theory is playing a key role in applied and pure mathematics. The scope of graph theory is expanding day by day. In this thesis we computed some topological coindices like as First and Second zagreb co-index, First and Second multiplicative zagreb coindex, Forgotton topological coindex, Atom bond connectivity coindex, Geometric arithmetic coindex and general Randic coindex for ∝= 1,−1, ଵ ଶ ,−ଵ ଶ for some chemical and networking graphs like as David derived network; ??(2), Dominating david derived network; ???(2), Regular Triangular Silicate network of dimension n; ????(?), Triangular chain cactus; ??, Oraganosilicon dendrimer ?[?]; ? ≥ 1; 2, Para chain square cactus; ?? ,Ortho chain square cactus; ??, Tetrathiafulvalene dendrimers; ??2[?]. My thesis comprising of four chapters. In the first chapter we will define some fundamental definitions. In the 2nd chapter, we will find Co-indices for David derived network, dominating David derived network, Regular triangular silicate network of dimension ? and Oraganosilicon dendrimer ?[?] graphs. In the 3rd chapter, we will find Triangular chain cactus, Para chain square cactus, Ortho chain square cactus, Tetrathiafulvalene dendrimers. In the 4th chapter, we will present the conclusion of our thesis. In the last, we will present the refrences of our thesis.Item On VE and EV Degree Based Topological Index of Graphs(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Aimen Wali; SP19-RMT-009; LHR TP 6469; Dr. Muhammad Kamran SiddiquiIn this dissertation, we calculated topological indices named ve-degree Zagreb alpha index, first ve-degree Zagreb beta index, second ve-degree Zagreb beta index, ve degree Randic index, ev-degree Randic index, ve-degree atom-bond connectivity index, ve-degree geometric-arithmetic index, ve-degree harmonic index and ve degree sum-connectivity index for Path graph, Cycle graph, Fan graph, Friendship graph, Complete graph, Jahangir graph, Generalized Petersen graph, Circulant graph, Sun graph, Wheel graph and Cartesian product of graph. In addition, we compared results of topological indices for each graph separately and represented it graphically.
