    Felicitous Labelings of Some Graphs

    Pages: 93-97
    Authors: V. Lakshmi Alias Gomathi
    A felicitous labeling of a graph G, with q edges is an injection  f : V(G) → {0, 1, 2,. . . , q} so  that  the  induced  edge  labels   f *(xy)  = (f(x) + f(y)) (mod q) are distinct.

    On Nonlocal Initial Problems for Fuzzy Differential Equations and Environmental Pollution Problems

    Pages: 77-92
    Authors: Nguyen Dinh Phu
    We present the properties of fuzzy solutions of the nonlocal initial problems for fuzzy differential equations under generalized Hukuhara differentiability (NIP for FIDEs) by the point of view of Hausdorff metric space, for example, existence, uniqueness, boundedness, ...  and stability of solutions. The different types of solutions NIP for  FDEs are generated by the usage of two different concepts of fuzzy derivative in the formulation of a differential problems. The examples are given to illustrate these results.
