Punk rock as popular theatre [PDF]

, 2007
Punk rock performance consciously draws on popular theatre forms like music hall and stand-up comedy, as exemplified by the occasion when Max Wall appeared with Ian Dury at the Hammersmith Odeon.

Frames generated by double sequences in Hilbert spaces [PDF]

Mathematica Moravica, 2023
In this paper, we introduce frames generated by double sequences (d-frame) in Hilbert spaces and describe some of their properties. Furthermore, we discuss frame operators, alternate dual frames and stability for d-frames.

Double Sequence Spaces Definedby a Sequence of Modulus Functions over $n$-normed Spaces [PDF]

, 2005
summary:In the present paper we introduce some double sequence spaces defined by a sequence of modulus function $ F = (f_{k,l})$ over $n$-normed spaces.

The Cesáro Core of Double Sequences [PDF]

Abstract and Applied Analysis, 2011
We have characterized a new type of core for double sequences, PC‐core, and determined the necessary and sufficient conditions on a four‐dimensional matrix A to yield PC‐core{Ax}⊆α(P‐core{x}) for all .

Matrix transformations of double convergent sequences with powers [PDF]

Proceedings of the Estonian Academy of Sciences
In 1967, I. J. Maddox generalized the spaces c0, c, ℓ∞ by adding the powers pk (k ∈ ℕ) in the definitions of the spaces to the terms of elements of sequences (xk). Gökhan and Çolak in 2004–2006 defined the corresponding double sequence spaces

F-seminorms on generalized double sequence spaces defined by modulus functions; pp. 121–132 [PDF]

Proceedings of the Estonian Academy of Sciences, 2014
Using a double sequence of modulus functions and a solid double scalar sequence space, we determine F-seminorm and F-norm topologies for certain generalized linear spaces of double sequences.

On Some New Sequence Spaces and Statistical Convergence Methods for Double Sequences

Demonstratio Mathematica, 2014
In this paper, we introduce some new double sequence spaces with respect to an Orlicz function and define two new convergence methods related to the concepts of statistical convergence and lacunary statistical convergence for double sequences.

e-core of double sequences [PDF]

Acta Mathematica Hungarica, 2014
Boos, Leiger and Zeller [1,2] defined the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for real double sequences and prove some fundamental properties of e-limit superior and inferior. In addition to these results we define e-core for double sequences. Also, we show that that if A is a nonnegative \(
