On summabilities (Aα) and (Ax). P. A. Jeyarajan has proved ([3], Theorem 4) the Tauberian theorem for generalized Abel summability (Aα) appearing as Theorem 1(Aα) in this note.- On a Theorem Connecting Borel and Cesaro Summabilities

R. D. Lord has generalized a classical theorem of Hardy and Little wood ([1], Theorem 156) and shown ([3], Theorem 5) that a sequence, summable by a method which is implied by Borel's, is summable also by Cesaro's method of a certain nonnegative order under an appropriate Tauberian condition.- Theorems on the Product of Two Summability Methods with Applications

My earlier note with the same title [3] was mainly about an extension of a theorem of Karamata on the Laplace- Abel transform to certain regular integral transforms Φ of a real function a(u) satisfying the classical one-sided condition,
a(u) u > - W, W > 0, for u > 1, and a(u) = 0 for u < 1. (1)

The principal object of this note is to generalize a one-sided Tauberian theorem of Karamata [3] for the Abel transform of a series. Implicit in the proof of the generalization there is a similar generalization of another one-sided Tauberian theorem, stated without proof by Vijayaraghavan [7, Theorem 8] for the Abel transform.- Cesaro Summability of a Glass of Functions

This note suggests a further use for a difference formula of L. S. Bosanquet which has already proved to be of service in dealing with certain problems involving Cesaro and Riesz means. More particularly, it is the object of the note to establish, by means of Bosanquet's formula, the integral analogue of a theorem on series, due to M. S. Macphail, [Theorem 2], which contains as a special case a result of H. L. Garabedian. Macphail's theorem itself can be obtained, as shown in the last section of the note, by an obvious adaptation of the argument used to prove its integral analogue.- On Periodic Meromorphic Functions

The first section of the note centres round the problem of constructing a periodic meromorphic function, with assigned poles and principal parts thereat, in a period strip. The second deals with rational functions of exp (2πiz/λ), the main theorem of the section giving a necessary and sufficient condition for a periodic meromorphic function to be such a rational function, in terms of its Nevanlinna characteristic function. Throughout it is supposed, for the sake of simplicity, that λ is a positive number.- Postscript to "Convergence Theorems for Series of Positive Terms"

In the paper cited above, I have based the convergence theory of positive series on
If O = d0 = D0, O<dn=Dn-Dn-1 (n = 1, 2,...), Dn→∞, and if F(x) is positive monotone decreasing, ∫ F(x)dx is convergent, then ∫dnF(Dn) is convergent.
The first result of this note leads to the more general companion.
