The total eccentric vertex degree is defined as: TE = Sigma()ev)(v is an element of E(G), where e(v) denotes the eccentric degree of the vertex v. The first Zagreb eccentric vertex degree alpha index is defined as: DM1 alpha = Sigma(ev2)(v is an element of E(G)). The first Zagreb eccentric vertex degree beta index is defined as: DM1 beta = Sigma((eu + ev))(uv is an element of E(G)). And the second Zagreb eccentric vertex degree index is defined as: DM2 = Sigma(euev)(uv is an element of E(G)). In this study, we compute the exact value of the Zagreb eccentric vertex degree indices of TUC4C8(S) nanotubes and TC4C8(S) nanotori.eninfo:eu-repo/semantics/closedAccessNanotubeNanotoriZagreb IndicesZagreb Eccentric Vertex Degree IndicesArticle
