Some remarks on Cesaro summability in neutrosophic normed spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
In this paper, we define the notion of a generalized summability, called Ces`aro summability in neutrosophic normed spaces (briefly NNS). We obtain conditions under which ordinary summability follows from Cesaro summability. Later, we define a concept of

ON \(A^{\mathcal{I^{K}}}\)–SUMMABILITY

open access: yesUral Mathematical Journal, 2022
In this paper, we introduce and investigate the concept of \(A^{\mathcal{I^{K}}}\)-summability as an extension of \(A^{\mathcal{I^{*}}}\)-summability which was recently (2021) introduced by O.H.H.~Edely, where \(A=(a_{nk})_{n,k=1}^{\infty}\) is a non ...

Some Results on Cesàro summability in Intuitionistic Fuzzy $n$-normed linear Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
The concept of summability plays a central role in finding formal solutions of partial differential equations. In this paper, we introduce the concept of Cesàro summability in an intuitionistic fuzzy $n$-normed linear space (IFnNLS).

Analytic continuation of solutions of some nonlinear convolution partial differential equations [PDF]

open access: yesOpuscula Mathematica, 2015
The paper considers a problem of analytic continuation of solutions of some nonlinear convolution partial differential equations which naturally appear in the summability theory of formal solutions of nonlinear partial differential equations.

On the Euler method of summability and concerning Tauberian theorems

open access: yesCumhuriyet Science Journal, 2021
For any two regular summability methods (U) and (V), the condition under which V-limx_n=λ implies U-limx_n=λ is called a Tauberian condition and the corresponding theorem is called a Tauberian theorem.

q-analogue of summability of formal solutions of some linear q-difference-differential equations [PDF]

open access: yesOpuscula Mathematica, 2015
Let \(q\gt 1\). The paper considers a linear \(q\)-difference-differential equation: it is a \(q\)-difference equation in the time variable \(t\), and a partial differential equation in the space variable \(z\). Under suitable conditions and by using \(q\

Pointwise approximation of modified conjugate functions by matrix operators of their Fourier series; pp 50-60 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2018
We extend the results presented by Xh. Z. Krasniqi (Slight extensions of some theorems on the rate of pointwise approximation of functions from some subclasses of Lp. Acta Comment. Univ. Tartu. Math., 2013, 17, 89–101) and W. Lenski and B.

Pythagorean harmonic summability of Fourier series

open access: yesDemonstratio Mathematica, 2021
This paper explores the possibility for summing Fourier series nonlinearly via the Pythagorean harmonic mean. It reports on new results for this summability with the introduction of new concepts like the smoothing operator and semi-harmonic summation ...

Summable orbits

open access: yesJournal of Modern Dynamics, 2023
We introduce a class of orbits which may have $0$ Lyapunov exponents, but still demonstrate some sensitivity to initial conditions. We construct a countable Markov partition with a finite-to-one almost everywhere induced coding, and which lifts the geometric potential with summable variations (for a $C^{1+}$ diffeomorphism of a closed manifold of ...

Strong summability methods in a Riesz-type family; pp. 238–250 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2011
We continue our studies on Riesz-type families of summability methods for functions and sequences, started in (Proc. Estonian Acad. Sci., 2008, 57, 70–80) and (Math. Model. Anal., 2010, 15, 103–112). Strong summability methods defined on the basis of
