Abstract:
Let S denote the class of analytic and univalent functions in of the form For α≥0, the subclass B_{1}α of S of Bazilevic functions has been extensively studied. In this paper we determine various properties of a subclass of B_{1}α, for α≥0 which extends early results of a class of starlike functions studied by Ram Singh.

Abstract:
Let f be analytic in D{z: z< 1} with , and normalized by the conditions f(0)=f'(0)1=0. We give sharp estimates for the seventh and eighth coefficients for the class of Bazilevic functions with logarithmic growth, B_{1}α, defined by for α≥0.

Abstract:
In this paper, we study the stability of epsilonisometry in the dual of real Banach spaces. We prove that the almost surjective epsilonisometry mapping is stable in dual of each spaces. The proof uses Gâteaux differentiability space (GDS), weakstar exposed points, normattaining operator, and some studies about epsilonisometry that have been done before.

Abstract:
We study the local boundedness of weak solutions for evolutional pLaplacian systems in the singular case. The initial data is belonging to Lebesgue space L^{∞} (0,T;W^{(1,p)} (Ω,R^{n} )). We use intrinsic scaling method to treat the boundedness of weak solutions. The main result is to make the local boundedness of weak solution for the systems wellworked in the intrinsic scaling.

Abstract:
We study about the Girsanov transformed for symmetric Markov processes with jumps associated with regular Dirichlet form. We prove the conservativeness of it by dividing the regular Dirichlet form into the "small jump" part and the "big jump" part.
