By a logarithmic change of coordinates, equation (2) is converted to a difference equation of type (1), and it can be concluded from Corollary 2.4 that (2) converges to maxA 1=ð12aiÞ i for all positive initial conditions. Max-type difference equations have been considered by a number of authors, including [1–9,11–14]. Ladas poses an interesting array of problems in [9]. Periodic and

On the periodic nature of some max-type difference equations
Recently there has been a lot of interest in studying the global attractivity, the boundedness character, and the periodicity nature of nonlinear difference equations. In [5, 6, 8] some global convergence results were established which can be applied to nonlinear difference equations in proving that every solution of these equations converges to a periodic solution (which need not necessarily b...
متن کاملConvergence analysis of the global FOM and GMRES methods for solving matrix equations $AXB=C$ with SPD coefficients
In this paper, we study convergence behavior of the global FOM (Gl-FOM) and global GMRES (Gl-GMRES) methods for solving the matrix equation $AXB=C$ where $A$ and $B$ are symmetric positive definite (SPD). We present some new theoretical results of these methods such as computable exact expressions and upper bounds for the norm of the error and residual. In particular, the obtained upper...
متن کاملA new model of (I+S)-type preconditioner for system of linear equations
In this paper, we design a new model of preconditioner for systems of linear equations. The convergence properties of the proposed methods have been analyzed and compared with the classical methods. Numerical experiments of convection-diffusion equations show a good im- provement on the convergence, and show that the convergence rates of proposed methods are superior to the other modified itera...
متن کاملHigh Order Compact Finite Difference Schemes for Solving Bratu-Type Equations
In the present study, high order compact finite difference methods is used to solve one-dimensional Bratu-type equations numerically. The convergence analysis of the methods is discussed and it is shown that the theoretical order of the method is consistent with its numerical rate of convergence. The maximum absolute errors in the solution at grid points are calculated and it is shown that the ...
