On Absolute q-Cesàro Summability Methods for Double Sequences
In the present paper, a novel absolute summability method, denoted by |Cq,θ|s, is introduced for double sequences via the q-Cesàro matrix. The study also focuses on determining the necessary and sufficient conditions for various inclusion relations, as ...

Absolute Nevanlinna Summability and Fourier Series [PDF]
We adopt here an extended version of the absolute Nevanlinna summability and apply it to study Fourier series of functions of bounded variations. The absolute Riesz summability |R,n,γ|, γ≥0, which is equivalent to the absolute Cesàro summability |C,γ ...

Spectral properties of substitutions on compact alphabets
Abstract We consider substitutions on compact alphabets and provide sufficient conditions for the diffraction to be pure point, absolutely continuous and singular continuous. This allows one to construct examples for which the Koopman operator on the associated function space has specific spectral components.

I-Cesàro summability of sequences of sets [PDF]
In this paper, we defined concept of Wijsman I-Cesàro summability for sequences of sets and investigate the relationships between the concepts of Wijsman strongly I-Cesàro summability, Wijsman strongly I-lacunary summability, Wijsman p-strongly I-Cesàro ...

Abstract Recently developed concept of dissipative measure‐valued solution for compressible flows is a suitable tool to describe oscillations and singularities possibly developed in solutions of multidimensional Euler equations. In this paper we study the convergence of the first‐order finite volume method based on the exact Riemann solver for the ...

Some inclusion theorems for absolute summability [PDF]
In this work the inclusion relations between absolute summability domains of a normal matrix A and certain factorable matrices are described. Thus, some classes of factorable matrices transforming the absolute summability domain of A into a set of ...
