Operators Approximable by Hypercyclic Operators [PDF]

open access: yesMathematical Proceedings of the Royal Irish Academy, 2015
We show that operators on a separable infinite dimensional Banach space $X$ of the form $I +S$, where $S$ is an operator with dense generalised kernel, must lie in the norm closure of the hypercyclic operators on $X$, in fact in the closure of the mixing operators.

Operator Symbols and Operator Indices [PDF]

open access: yesSymmetry, 2019
We suggest a certain variant of symbolic calculus for special classes of linear bounded operators acting in Banach spaces. According to the calculus we formulate an index theorem and give applications to elliptic pseudo-differential operators on smooth manifolds with non-smooth boundaries.
