In this paper, we introduce and investigate the concept of conformable delta fractional derivative on time scales. By using the theory of time scales, we obtain some basic properties of the conformable delta fractional derivative. Our results extend and improve both the results in [9] and the usual delta derivative.     

A Fixed Point Theorem and its Application to Best Approximation

The object of this paper is twofold. First, a fixed point theorem of G.L. Cain, Jr. and M. Z. Nashed [1] is generalized. Second, the theorem (Theoreml) is utilized to obtain theorems on best approximation which extend and unify the results of Meinardus [2], Singh [ 3—4 ], and Sahney Singh-Whitfield [5].     

EXCESS FUNCTIONS OF RAYS ON COMPLETE NONCOMPACT MANIFOLDS

This paper gives an estimate of excess functions of rays on complete noncompact manifolds. By using this estimation, the authors can get the results in [3] as corollaries, which asserts that a complete manifold is diffeomorphic to R^n under some curvature and pinching conditions. At last, they obtain a refinement of them with extra Ricci condition.

Loewner Chains and Univalence criteria related with Ruscheweyh and Salagean derivatives

In this paper we obtain, by the method of Loewner chains, some sufficient conditions for the analyticity and the univalence of the functions defined by an integral operator. These conditions involves Ruscheweyh and Salagean derivative operator in the open unit disk. In particular cases, we find the well-known conditions for univalency established by Becker [3], Ahlfors [2], Kanas and Srivastava [8] and others for analytic mappings f : U ! C: Also,we obtain the corresponding new, useful and simpler conditions for this integral operator.     

Construction of an interpolant operator: Application to the three-dimensional electrostatic problem

We propose in Zaghdani (2006) [2] and Zaghdani and Daveau (in press) [3], a discontinuous Galerkin formulation with a mixed setting. In this paper, we construct an interpolant on a discontinuous space to obtain the inf–sup condition which is necessary to show that the formulation is well posed.
