Closedness of the orbit-closed $C$ -numerical range and submajorization

Jireh Loreaux, Sasmita Patnaik

For a positive trace-class operator $C$ and a bounded operator $A$ , we provide an explicit description of the closure of the orbit-closed $C$ -numerical range of $A$ in terms of tho…

Matrix splitting and ideals in $B (H)$

Jireh Loreaux, Gary Weiss

We investigate the relationship between ideal membership of an operator and its pieces relative to several canonical types of partitions of the entries of its matrix representation…
