Matrix transformations of Norlund–Orlicz difference sequence spaces of nonabsolute type and their Toeplitz duals

open access: yesAdvances in Difference Equations, 2020
In this paper, the Nörlund–Orlicz difference sequence space N t ( F , Δ n m , u , q ) $\mathcal{N}^{t}(\mathcal{F},\Delta^{m}_{n},u,q)$ of nonabsolute type is introduced as a domain of Nörlund means which is isomorphic to the space ℓ ( p ) $\ell(p)$ and ...

Binomial difference sequence spaces of order m

open access: yesAdvances in Difference Equations, 2017
In this paper, we introduce the binomial sequence spaces b 0 r , s ( ∇ ( m ) ) $b^{r,s}_{0}(\nabla^{(m)})$ , b c r , s ( ∇ ( m ) ) $b^{r,s}_{c}(\nabla^{(m)})$ and b ∞ r , s ( ∇ ( m ) ) $b^{r,s}_{\infty}(\nabla^{(m)})$ by combining the binomial ...

Review on Some Sequence Spaces of p-adic Numbers [PDF]

open access: yesEurasian Journal of Science and Engineering, 2017
In this paper, we make a literature review on p-adic sequences and we prove some new topological properties on the sequence spaces w(p), l∞(p) and c(p) of p-adic numbers as the set of all sequences, the set of bounded sequences and the set of convergent ...

α,β‐Unsaturated γ‐Peptide Foldamers

open access: yes, 2021
International audienceDespite their concomitant emergence in the 1990s, γ‐peptide foldamers have not developed as fast as β‐peptide foldamers and to date, only a few γ‐oligomer structures have been reported, and with sparse applications.

Biologically Active Compounds. IV. The Synthesis of α-Arylamino-γ-aryl-⊿(α,β)- and α-Arylidene-γ-aryl-⊿(β,γ)-butenolides. [PDF]

open access: yes, 1970
The importance of the presence of butenolide groupings in biologically active substances has been recognized increasingly. (1) In our search for new pesticides we have prepared 26 α-arylamino-γ-aryl-⊿(α,β)-butenolides (1-26) and 9 α-arylidene-γ-aryl-⊿(α ...

Some Additions to the Fuzzy Convergent and Fuzzy Bounded Sequence Spaces of Fuzzy Numbers

open access: yesAbstract and Applied Analysis, 2011
Some properties of the fuzzy convergence and fuzzy boundedness of a sequence of fuzzy numbers were studied in Choi (1996). In this paper, we have consider, some important problems on these spaces and shown that these spaces are fuzzy complete module ...

Helix Formation in α,γ- and β,γ-Hybrid Peptides:  Theoretical Insights into Mimicry of α- and β-Peptides

open access: yes, 2016
α,γ- and β,γ-hybrid peptides, which are composed of two different homologous amino acid constituents in alternate order, are suggested as novel classes of peptide foldamers.

Mappings Ideal of Type the Domain of Generalized p,q-Euler Matrix in c0 and c

open access: yesJournal of Mathematics, 2023
We develop new Banach sequence spaces e0a,bp,q and eca,bp,q derived by the domain of generalized p,q-Euler matrix Ea,bp,q in the spaces of null and convergent sequences, respectively.

On New Banach Sequence Spaces Involving Leonardo Numbers and the Associated Mapping Ideal

open access: yesJournal of Function Spaces, 2022
In the present study, we have constructed new Banach sequence spaces ℓpL,c0L,cL, and ℓ∞L, where L=lv,k is a regular matrix defined by lv,k=lk/lv+2−v+2, 0≤k≤v,0, k>v, for all v,k=0,1,2,⋯, where l=lk is a sequence of Leonardo numbers.
