Abstract:
In this paper we give a complete proof of A method for the solution of fractional transport equation in three-dimensional case by using Walsh function is presented. The main characteristic of this technique is that it reduces these problems to those of solving a system of algebraic equations, thus greatly simplifying the problem.

Abstract:
For any positive integer n a new family of periodic functions in power series form and
of period n is used to solve in closed form a class of polynomial equations of order
n. The n roots are the values of the appropriate function from that family taken at
0, 1, ... , n-1.

Abstract:
In this paper we derive comparison results for Hermitian solutions of time scale matrix Riccati
equations and Riccati inequalities. Such solutions arise from special conjoined bases
(X,U) of the corresponding time scale symplectic system via the Riccati quotient
. We also discuss properties of a unitary matrix solution of a certain
associated Riccati equation.

Abstract:
In this paper, we study variational inequalities related to ergodic control problems studied by M. Boulbrachène and H. Sissaoui [11], where the "discount factor" (i.e., the zero order term) is set to 0, we use an overlapping Schwarz method on nomatching grid which consists in decomposing the domain in two subdomains. For α ∈ ]0.1[ we provide the discretization on each subdomain converges in L∞ -norm.

Abstract:
We prove existence of weak solutions of stochastic Navier-Stokes equations in R2 which do not satisfy the coercivity condition. The equations are formally derived from the critical point of some variational problem defined on the space of volume preserving diffeomorphisms in R2. Since the domain of our equation is unbounded, it is more difficult to get tightness of approximating sequences of solutions in comparison with the case of a bounded domain. Our approach is based on uniform a priori estimates on the enstrophy of weak solutions of the stochastic 2D-Navier-Stokes equations with periodic boundary conditions, where the periodicity is growing to infinity combined with a suitable spatial cutoff-technique.

Abstract:
In the present paper, some best proximity results have been presented using the concept of G-Presic type multi-valued mapping. These results are the extensions of Presic's theorem in the non-self mapping. A suitable example has also been given. Here, some applications are presented in θ-chainable space and ordered metric space.
