Projections in operator ranges [PDF]
, 2005 If $\H$ is a Hilbert space, $A$ is a positive bounded linear operator on $\cH$ and $\cS$ is a closed subspace of $\cH$, the relative position between $\cS$ and $A^{-1}(\cS \orto)$ establishes a notion of compatibility. We show that the compatibility of $(

On the H^1-L^1 boundedness of operators
, 2008 We prove that if q is in (1,\infty), Y is a Banach space and T is a linear operator defined on the space of finite linear combinations of (1,q)-atoms in R^n which is uniformly bounded on (1,q)-atoms, then T admits a unique continuous extension to a ...

Computing the q-Numerical Range of Differential Operators
Journal of Applied Mathematics, 2020 A linear operator on a Hilbert space may be approximated with finite matrices by choosing an orthonormal basis of thez Hilbert space. In this paper, we establish an approximation of the q-numerical range of bounded and unbounnded operator matrices by ...

Continuity of Bounded Linear Operators on Normed Linear Spaces [PDF]
Formalized Mathematics, 2018 Summary In this article, using the Mizar system [1], [2], we discuss the continuity of bounded linear operators on normed linear spaces. In the first section, it is discussed that bounded linear operators on normed linear spaces are uniformly continuous and Lipschitz continuous.

A generalized Schur complement for non-negative operators on linear space
, 2017 Extending the corresponding notion for matrices or bounded linear operators on a Hilbert space we define a generalized Schur complement for a non-negative linear operator mapping a linear space into its dual and derive some of its ...

Dilations of frames, operator valued measures and bounded linear maps
, 2014 We will give an outline of the main results in our recent AMS Memoir, and include some new results, exposition and open problems. In that memoir we developed a general dilation theory for operator valued measures acting on Banach spaces where operator ...

Computation of antieigenvalues of bounded linear operators via centre of mass
, 2013 We introduce the concept of theta-antieigenvalue and theta-antieigenvector of a bounded linear operator on complex Hilbert space. We study the relation between theta-antieigenvalue and centre of mass of a bounded linear operator and compute ...

Bounded evaluations for linear elliptic differential operators [PDF]
Proceedings of the American Mathematical Society, 1973 Bounds for point evaluations are obtained for spaces of solutions of elliptic partial differential equations on generalized "Swiss cheese" compacta in Euclidean space. In this way we generalize recent approximation theorems for differential operators due to Polking.
