Edge Trimagic Total Labeling for Disconnected Graphs
Journal Title: INTERNATIONAL JOURNAL OF MATHEMATICS TRENDS AND TECHNOLOGY - Year 2014, Vol 6, Issue 1
Abstract
An edge trimagic total labeling of a graph G(V, E) with p vertices and q edges is a bijection f from the set of vertices and edges to 1, 2, … , p+q such that for every edge uv in E, f(u)+f(uv)+f(v) is either 1 or 2 or 3. An edge trimagic total graph is called a super edge trimagic total if f(V) = {1, 2, . . ., p}. An edge trimagic total graph is called a superior edge trimagic total if f(E) = {1, 2, . . ., q}. In this paper we prove the disconnected graphs nP3, (K1, pK1, qK1, r), nP2K1, n+1, t copies of the sun graph Sn, nC4 and nC6 admits edge trimagic total labeling.

Numerical Solution of Fuzzy Differential Equations by Extended Runge-Kutta Method and the Dependency Problem
In this paper we use extended Runge-Kutta-like formulae of order four (ERK4) and of order five (ERK5) by taking into account the dependency problem that arises in fuzzy setting. This method is adopted to solve the depend...
