Linear difference and differential operators with unbounded operator coefficients in weight spaces

Mathematical Notes, 2009
Let \(X\) be a complex Banach algebra, \(B(X)\) the set of all bounded linear operators on \(X\), \(\alpha : \mathbb{Z}_+ \to (0, \infty)\) a weight function, \(\ell_{\alpha}^p\) the Banach space of sequences \(x : \mathbb{Z}_+ \to X\) from \(X\), summable with weight \(\alpha\), \(\|x\| = \|x\|_{p,\alpha} = (\sum_{n\geq 0}(\|x(n)\|/ \alpha (n))^p)^{1 ...

Fractional difference operators with discrete generalized Mittag–Leffler kernels

Chaos, Solitons & Fractals, 2019
In this article we define fractional difference operators with discrete generalized Mittag–Leffler kernels of the form ( E θ , μ ¯ γ ( λ , t − ρ ( s ) ) for both Riemann type (ABR) and Caputo type (ABC) cases, where AB stands for Atangana–Baleanu.

Discrete generalized fractional operators defined using h‐discrete Mittag‐Leffler kernels and applications to AB fractional difference systems

Mathematical methods in the applied sciences, 2020
This study investigates the h‐fractional difference operators with h‐discrete generalized Mittag‐Leffler kernels ( hEϕ,δ‾ω(Θ,t−ρh(sh)) in the sense of Riemann type (namely, the ABR) and Caputo type (namely, the ABC). For which, we will discuss the region

Difference schr�dinger operators with linear and exponential discrete spectra

Letters in Mathematical Physics, 1993
Here the authors by using the factorization method, construct finite- difference Schrödinger operators (Jacobi matrices) whose discrete spectra are composed from independent arithmetic, or geometric series. These systems originate from the periodic, or \(q\)-periodic closure of a chain of corresponding Darboux transformations. The Charlier, Krawtchouk,
