On symmetric and approximately symmetric operators
Divya Khurana
We introduce the notion of local orthogonality preserving operators to study the right-symmetry of operators. As a consequence of our work, we show that any smooth compact operator…

On approximately orthogonality preserving and reversing operators
Divya Khurana
We study approximately orthogonality (in the sense of Dragomir) preserving and reversing operators. We show that for some orthogonality notations, an operator defined from a finite…
