SOLVING NONLINEAR KLEINGORDON EQUATION WITH A QUADRATIC NONLINEAR TERM USING HOMOTOPY ANALYSIS METHOD
2
2
In this paper, nonlinear KleinGordon equation with quadratic term is solved by means of an analytic technique, namely the Homotopy analysis method (HAM).Comparisons are made between the Adomian decomposition method (ADM), the exact solution and homotopy analysis method. The results reveal that the proposed method is very effective and simple.

APPLICATION OF EXPFUNCTION METHOD TO THE (2+1)DIMENSIONAL CALOGERO BOGOYAVLANSKII SCHIFF EQUATION
2
2
In this paper, the Expfunction method, with the aid of a symbolic computation system such as Maple, is applied to the (2+1) dimensional Calogero Bogoyavlanskii Schiff equation. Exact and explicit generalized solitary solutions are obtained in more general forms. The free parameters can be determined by initial or boundary conditions. The method is straightforward and concise, and its applications are promising. It is shown that the Expfunction method, with the help of symbolic computation, provides a very effective and powerful mathematical tool for solving Calogero Bogoyavlanskii Schiff equation.

DECOMPOSITION METHOD FOR SOLVING FULLY FUZZY LINEAR SYSTEMS
2
2
In this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. This paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (ST) decomposition. By this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix S and a fuzzy triangular matrix T.
