Richard P. Gallagher,J. Mark ElwoodThe theory of matrix transformations deals with establishing necessary and sufficient conditions on the entries of a matrix to map a sequence space . into a sequence space .. This is a natural generalization of the problem to characterize all summability methods given by infinite matrices that preserve convergence.

https://doi.org/10.1007/978-3-642-71043-8In this chapter we apply regular and almost regular matrices to find the sum of derived Fourier series, conjugate Fourier series, and Walsh-Fourier series (see and ). Recently, Móricz has studied statistical convergence of sequences and series of complex numbers with applications in Fourier analysis and summability.

Lototski Summability and Analytic Continuation,Analytic continuation is a technique to extend the domain of a given analytic function. Analytic continuation often succeeds in defining further values of a function, for example, in a new region where an infinite series representation in terms of which it is initially defined becomes divergent.
