Abstract:
In this short note we prove a conjecture, related to a logarithmically completely monotonic function, presented in [5]. Then, we extend by proving a more generalized theorem. At the end we pose an open problem on a logarithmically completely monotonic function involving qDigamma function.

Abstract:
Mubeen et al. obtained Kummer's first transformation for the khypergeometric function. The aim of this note is to provide the Eulertype first transformation for the khypergeometric function. As a limiting case, we recover the results of Mubeen et al. In addition to this, an alternate and easy derivation of Kummer's first transformation for the khypergeometric function is also given.

Abstract:
In this paper we prove analogous theorems like Leindler's 3 using the socalled Atransform of the Btransform of the partial sums of Fourier series. In addition, more than two such transforms are introduced and for them analogous results are showed as well.

Abstract:
In this paper we have introduced some new trigonometric polynomials. Using these polynomials, we have proved some theorems which determine the degree of approximation of periodic functions by a product of two special means of their Fourier series and the conjugate Fourier series. Many results proved previously by others are special case of ours.
