چکیده

On a Lebesgue measure space with measure element do, and total measure finite or infinite, we consider the complex-valued measurable functions f, y, so, ., each determined only a.e., and each belonging to all L,-classes simultaneously, 1<r< a. We donote (i) by F = {f} a ring of functions with complex constants and ordinary multiplication and closed under the involution: if f -= f + if2 e F then also fe fiif2 e F and hence also fi, f2 e F; (ii) by r = { I a subring of F also closed under this involution; (iii) by CD = {so} another subring but this one not closed under the involution; (iv) by + = {sr} the ring of elements conjugate complex to those of CD, and we make the following interlocking assumptions; (v) if y e F, (p E 4 then 'yp 4), and thus, by involution in r, also y~p e 5, (vi) for all so e ¢, f ~pq= 0.

The Lerch Transcendent from the Point of View of Fourier Analysis

We obtain some well-known expansions for the Lerch transcendent and the Hurwitz zeta function using elementary Fourier analytic methods. These Fourier series can be used to analytically continue the functions and prove the classical functional equations, which arise from the relations satisfied by the Fourier conjugate and flat Fourier series. In particular, the functional equation for the Riem...

An Analytic Method for Convergence Acceleration of Certain Hypergeometric Series

A method is presented for convergence acceleration of the generalized hypergeometric series 3F2 with the argument ±1 , using analytic properties of their terms. Iterated transformation of the series is performed analytically, which results in obtaining new fast converging expansions for some special functions and mathematical constants.

Identification of Initial Taylor-Maclaurin Coefficients for Generalized Subclasses of Bi-Univalent Functions

In the present work, the author determines some coefficient bounds for functions in a new class of analytic and bi-univalent functions, which are introduced by using of polylogarithmic functions. The presented results in this paper one the generalization of the recent works of Srivastava et al. [26], Frasin and Aouf [13] and Siregar and Darus [25].
