In this paper, we will discuss the problem of min- max zero sum two persons fuzzy continuous differential game with fuzzy controls and its membership is a non linear function. The necessary and sufficient conditions for this problem are derived. Finally, numerical example is presented to verify the results.

In  this  paper, we  introduce  a  new  class  of  sets  G^#P-Locally  closed  sets, G^#P-Locally  closed  functions  and  their  properties.

In this paper we are inspired by the work of Young Bae Jun and Kyung  Ho Kim. We introduce another definition of the notion of ideal of a subtraction  algebra, which infers then a different notion of prime ideal.  This notion leaves the principle that if an ideal contains an element it  contains all the elements which are lower than it, while that proposed  in  the paper quoted previously if an element y is in the ideal and if the element  x – y  is in the ideal then x is also in the ideal. Certain results steel valid in our case. We think that the definitions which we introduced are less restrictive than those of Young Bae Jun and Kyung Ho Kim. We introduce besides the notion of morphism of a subtraction algebra and establish some relative characterizations of the kernels of such morphisms.

In this paper, we will study    Z =  and  Z =    type plane gravitational waves with the matter cosmic strings in the context of Rosen’s Bimetric theory of relativity and observed that the cosmic strings does not exist in this theory.

The objective of the present chapter is to analyze the radiation and mass transfer effects on an unsteady two-dimensional laminar mixed convective boundary layer flow of a viscous, incompressible, electrically conducting chemically reacting fluid, along a vertical moving semi-infinite permeable plate with suction, embedded in a uniform porous medium, in the presence of transverse magnetic field. The equations of continuity, linear momentum, energy and diffusion, which govern the flow field, are solved by using a regular perturbation method.  The behavior of the velocity, temperature, concentration, skin-friction, Nusselt number and Sherwood number has been discussed for variations in the governing parameters.
