The Algebra of Compact-by-Approximable Operators on Banach Spaces [PDF]
, 2022 This doctoral dissertation is devoted to the study of the quotient algebra of compact-by-approximable operators (the compact-by-approximable algebra) on Banach spaces and related quotient algebras of linear operators.

Decaying and non-decaying badly approximable numbers [PDF]
, 2016 We call a badly approximable number $decaying$ if, roughly, the Lagrange constants of integer multiples of that number decay as fast as possible. In this terminology, a question of Y.

Spectral approximants of normal operators [PDF]
Proceedings of the Edinburgh Mathematical Society, 1974 For each non-empty subset Λ of the complex plane, let (Λ) be the set of all those operators (on a fixed Hilbert space H) whose spectrum is included in Λ. The problem of spectral approximation is to determine how closely each operator on H can be approximated (in the norm) by operators in (Λ).

On polynomial approximation of the inverseof an operator
Linear Algebra and its Applications, 2004 The author gives a necessary and sufficient condition for the inverse of \(A\) to be the uniform limit of polynomials in \(A\). He discusses the same problem for the strong and weak operator topologies.

Approximation by Max-Product Operators
Fasciculi Mathematici, 2018 Abstract Here we study the approximation of functions by a great variety of Max-Product operators under differentiability. These are positive sublinear operators. Our study is based on our general results about positive sublinear operators. We produce Jackson type inequalities under initial conditions.
