In the fall of 2017, Mehtaab Sawhney, then an undergraduate at the Massachusetts Institute of Technology, joined a graduate reading group that set out to study a single paper over a semester. But by ...

We simplify the negative solution to the invariant subspace problem for Banach spaces. Developing the ideas of Read, we give an explicit example of a continuous linear operator on the Banach space l₁ ...

This paper is a continuation of our recent work on super-recurrence of operators [3]. We introduce and study subspace-super recurrence of operators. We give the relationship between this new class of ...
