Continuous linear operators on Orlicz-Bochner spaces
Open Mathematics, 2019 Let (Ω, Σ, μ) be a complete σ-finite measure space, φ a Young function and X and Y be Banach spaces. Let Lφ(X) denote the corresponding Orlicz-Bochner space and Tφ∧$\begin{array}{} \displaystyle \mathcal T^\wedge_\varphi \end{array}$ denote the finest ...

On sums of narrow and compact operators
Positivity (Dordrecht), 2019 We prove, in particular, that if E is a Dedekind complete atomless Riesz space and X is a Banach space then the sum of a narrow and a C-compact laterally continuous orthogonally additive operators from E to X is narrow.

A property of compact operators [PDF]
Proceedings of the American Mathematical Society, 1984 The present paper is inspired by the work of \textit{V. F. Babenko} and \textit{S. A. Pichugov} [Ukr. Mat. Zh. 33, 491-492 (1981; Zbl 0492.47018)] and that of \textit{I. K. Daugavet} [Usp. Mat. Nauk. 18, No.5(113), 157-158 (1963; Zbl 0138.386)]. They proved that if T is any compact linear operator on either of the Banach spaces \(L^ 1(0,1)\) or C[0,1],

On the Lattice Properties of Almost L-Weakly and Almost M-Weakly Compact Operators
Journal of Function Spaces, 2021 We establish the domination property and some lattice approximation properties for almost L-weakly and almost M-weakly compact operators. Then, we consider the linear span of positive almost L-weakly (resp., almost M-weakly) compact operators and give ...

The version for compact operators of Lindenstrauss properties A and B [PDF]
, 2015 It has been very recently discovered that there are compact linear operators between Banach spaces which cannot be approximated by norm attaining operators.

The Bidual of the Compact Operators [PDF]
Transactions of the American Mathematical Society, 1985 For a Banach space X, let \(X^*\) be the dual, B(X) the Banach algebra of bounded linear operators, and \(B_ F(X)\), \(B_ K(X)\) and \(B_ I(K)\) the ideals of finite rank, compact, and integrable operators, respectivly. \textit{A.

Modified Novikov Operators and the Kastler-Kalau-Walze-Type Theorem for Manifolds with Boundary
Advances in Mathematical Physics, 2020 In this paper, we give two Lichnerowicz-type formulas for modified Novikov operators. We prove Kastler-Kalau-Walze-type theorems for modified Novikov operators on compact manifolds with (respectively without) a boundary.

Nonlinear eigenvalue approximation for compact operators [PDF]
, 2014 In the work of Osborn [Math. Comput. 29, 712–725 (1975)], a general spectral approximation theory was developed for compact operators on a Banach space which does not require that the operators be self-adjoint and also provides a first order correction ...

Approximations of set-valued functions based on the metric average [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2006 This paper investigates the approximation of set-valued functions with compact images (not necessarily convex), by adaptations of the Schoenberg spline operators and the Bernstein polynomial operators.

The Gâteaux derivative and orthogonality in C∞
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 The general problem in this paper is minimizing the C∞− norm of suitable affine mappings from B(H) to C∞, using convex and differential analysis (Gateaux derivative) as well as input from operator theory.
