On Some Analytic Functions Defined by a Multiplier Transformation
International Journal of Mathematics and Mathematical Sciences, Volume 2007, Issue 1, 2007., 2007 We introduce and study a new class of analytic functions defined in the unit disc using a certain multiplier transformation. Some inclusion results and other interesting properties of this class are investigated.

N‐harmonic extensions of weighted integrable distributions
Journal of Function Spaces, Volume 4, Issue 3, Page 305-327, 2006., 2006 We obtain n‐harmonic extensions to the Cartesian product of ncopies of the upper half‐plane, of distributions in the weighted space w12?wn2DL1′, which is known to be the optimal space of tempered distributions that are S′‐convolvable with a natural product domain version of the Poisson kernel.

Some special cases on Stolarsky’s means
Ratio MathematicaIn this paper we observe that one-parameter Stolarsky’s means (SM) are deduced from both the Mean Value Theorem for derivatives (MVTD) and the Mean Value Theorem for definite integrals (MVTI), and we study their elementary properties as the parameter ...

On inclusion relations for absolute summability
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 3, Page 129-138, 2002., 2002 We obtain necessary and (different) sufficient conditions for a series summable |N¯,pn|k, 1 < k ≤ s < ∞, to imply that the series is summable |T|s, where (N¯,pn) is a weighted mean matrix and T is a lower triangular matrix. As corollaries of this result, we obtain several inclusion theorems.

On certain classes of meromorphically starlike functions
International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 3, Page 463-467, 1995., 1994 The object of the present paper is to introduce a new class ∑n(α) of meromorphic functions defined by a multiplier transformation and to investigate some properties for the class ∑n(α) Further we study integrals of functions in ∑n(α).

Mean value problems of Flett type for a Volterra operator
Electronic Journal of Differential Equations, 2013 In this note we give a generalization of a mean value problem which can be viewed as a problem related to Volterra operators. This problem can be seen as a generalization of a result concerning the zeroes of a Volterra operator in the Banach space of ...
