چکیده

For a regularly converging-in-C series A(z)=?n=1?anf(?nz), where f is an entire transcendental function, the asymptotic behavior of function Mf?1(MA(r)), Mf(r)=max{|f(z)|:|z|=r}, investigated. It proven that, under certain conditions on functions f, ?, and coefficients an, equality limr?+??(Mf?1(MA(r)))?(r)=1 correct. A similar result obtained for Laplace–Stiltjes-type integral I(r)=?0?a(x)f(rx)dF(x). Unresolved problems are formulated.

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...

Relative order and type of entire functions represented by Banach valued Dirichlet series in two variables

In this paper, we introduce the idea of relative order and type of entire functions represented by Banach valued Dirichlet series of two complex variables to generalize some earlier results. Proving some preliminary theorems on the relative order, we obtain sum and product theorems and we show that the relative order of an entire function represented by Dirichlet series is the same as that of i...

Series expansion of Wiener integrals via block pulse functions

In this paper, a suitable numerical method based on block pulse functions is introduced to approximate the Wiener integrals which the exact solution of them is not exist or it may be so hard to find their exact solutions. Furthermore, the error analysis of this method is given. Some numerical examples are provided which show that the approximation method has a good degree of accuracy. The main ...
