Spectral properties of non-local uniformly-elliptic operators [PDF]

, 2006
In this paper we consider the spectral properties of a class of non-local uniformly elliptic operators, which arise from the study of non-local uniformly elliptic partial differential equations. Such equations arise naturally in the study of a variety of

Convergence Properties of Certain Positive Linear Operators [PDF]

, 2019
The present paper deals with the modified positive linear operators that present a better degree of approximation than the original ones. This new construction of operators depend on a certain function defined on [0, 1].

Approximation of unbounded functions by linear positive operators [PDF]

, 1996
A unified class of linear positive operators has been defined. Using these operators some approximation estimates have been obtained for unbounded functions.

Approximation by generalized positive linear Kantorovich operators [PDF]

, 2017
In the present article, we introduce generalized positive linear-Kantorovich operators depending on P?lya-Eggenberger distribution (PED) as well as inverse P?lya-Eggenberger distribution (IPED) and for these operators, we study some ...

Resolvent compositions for positive linear operators

Positivity
Abstract Resolvent compositions were recently introduced as monotonicity-preserving operations that combine a set-valued monotone operator and a bounded linear operator. They generalize in particular the notion of a resolvent average. We analyze the resolvent compositions when the monotone operator is a positive linear operator.

Positive and Z-operators on Closed Convex Cones [PDF]

, 2018
Let $K$ be a closed convex cone with dual $\dual{K}$ in a finite-dimensional real Hilbert space. A \emph{positive operator} on $K$ is a linear operator $L$ such that $L\of{K} \subseteq K$.
