Hermite-Hadamard type inequalities for operator geometrically convex functions [PDF]
, 2015 In this paper, we introduce the concept of operator geometrically convex functions for positive linear operators and prove some Hermite-Hadamard type inequalities for these functions. As applications, we obtain trace inequalities for operators which give

Eventually positive semigroups of linear operators
Journal of Mathematical Analysis and Applications, 2016 We develop a systematic theory of eventually positive semigroups of linear operators mainly on spaces of continuous functions. By eventually positive we mean that for every positive initial condition the solution to the corresponding Cauchy problem is positive for large enough time.

The Θ-transformation of certain positive linear operators
International Journal of Mathematics and Mathematical Sciences, 1996 The intention of this paper is to describe a construction method for a new sequence of linear positive operators, which enables us to get a pointwise order of approximation regarding the polynomial summator operators which have best properties of ...

Approximation of functions of two variables by certain linear positive operators
, 2007 We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables.

Maps preserving absolute continuity and singularity of positive operators [PDF]
, 2020 In this paper we consider the cone of all positive, bounded operators acting on an infinite dimensional, complex Hilbert space, and examine bijective maps that preserve absolute continuity in both directions.

A characterization of positive linear maps and criteria of entanglement for quantum states
, 2010 Let $H$ and $K$ be (finite or infinite dimensional) complex Hilbert spaces. A characterization of positive completely bounded normal linear maps from ${\mathcal B}(H)$ into ${\mathcal B}(K)$ is given, which particularly gives a characterization of ...

On New Classes of Stancu-Kantorovich-Type Operators
Mathematics, 2021 The present paper introduces new classes of Stancu–Kantorovich operators constructed in the King sense. For these classes of operators, we establish some convergence results, error estimations theorems and graphical properties of approximation for the ...
