نویسنده
چکیده
The problem of two-dimensional, steady, nonlinear flow of an incompressible conducting viscous fluid in convergent-divergent channels under the influence of an externally applied homogeneous magnetic field is studied using a special type of Hermite-Padé approximation approach. This semi-numerical scheme offers some advantages over solutions obtained by using traditional methods such as finite differences, spectral method, shooting method, etc. It reveals the analytical structure of the solution function and the important properties of overall flow structure including velocity field, flow reversal control and bifurcations are discussed.

We have studied by means of Monte-Carlo simulation and exact finite-size analysis, the spin-1 Blume Capel model with Glauber and Kawasaki dynamics. The Kawasaki spin exchange process flows energy into the system from an external source. Some phase diagrams of the model are presented. For some values of the parameters, the system displays a kind of self organization phenomenon within the disorde...

Some random fixed point theorems for set-valued random operators under very mild conditions are established. Some recent results of O'Regan ([Proc. Amer. Math. Soc. 126 (1998), 3045-3053] and [Computers Math. Applic. 35 (1998), 27-34]) are improved significantly. The discussion in this paper underlines, in addition to generality, the unifying aspects of our result.
