On the fine spectra of the generalized difference operator $\Delta_{uv}$ over the sequence space $c_0$ [PDF]
Journal of Mahani Mathematical Research, 2012 The main purpose of this paper is to detemine the fine spectrum of the generalized difference operator $\Delta_{uv}$ over the sequence space c0. These results are more general than the fine spectrum of the generalized difference operator $\Delta_{uv}$ of

Spectrum and fine spectrum of the lower triangular matrix B r s t , , over the sequence space cs [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 Fine spectra of various matrix operators on different sequence spaces have been examined by several authors. Recently, some authors have determined the approximate point spectrum, the defect spectrum and the compression spectrum of various matrix ...

Hahn Sequence Space of Modals [PDF]
International Scholarly Research Notices, 2014 The history of modal intervals goes back to the very first publications on the topic of interval calculus. The modal interval analysis is used in Computer graphics and Computer Aided Design (CAD), namely, the computation of narrow bounds on Bezier and B-Spline curves.

Solvability of an infinite system of nonlinear integral equations of Volterra-Hammerstein type
Advances in Nonlinear Analysis, 2019 The purpose of the paper is to study the solvability of an infinite system of integral equations of Volterra-Hammerstein type on an unbounded interval. We show that such a system of integral equations has at least one solution in the space of functions ...

On Certain Sequence Spaces [PDF]
Canadian Mathematical Bulletin, 1981 AbstractIn this paper define the spaces l∞(Δ), c(Δ), and c0(Δ), where for instance l∞(Δ) = {x=(xk):supk |xk -xk + l|< ∞}, and compute their duals (continuous dual, α-dual, β-dual and γ-dual). We also determine necessary and sufficient conditions for a matrix A to map l∞(Δ) or c(Δ) into l∞ or c, and investigate related questions.
