In this paper, we have studied the peristaltic MHD flow of an incompressible, electrically conducting Williamson fluid in a symmetric planner channel through a porous medium with heat and mass transfer under the influence of inclined magnetic field of an angle of inclination  and taking hall current into account. Viscous dissipation and Joule heating are also taken into consideration.  The non linear partial differential equations that govern that model were simplified under assumptions of long wavelength and low Reynolds number. Then a regular perturbation technique in the Weissenberg number was applied to obtain a closed form expressions for stream function, axial pressure gradient, temperature and concentration profiles. The influence of various parameters on the flow was discussed.

In this paper, we define some new types of separation axioms in topological spaces by using ag*p-open sets. Several properties of these spaces are investigated. Further we introduce the concepts of ag*p-normal , ag*p-regular spaces and obtain some of their properties.
