Disjointly non-singular operators: Extensions and local variations

Manuel González, Antonio Martinón

The disjointly non-singular ( $D N S$ ) operators $T \in L (E, Y)$ from a Banach lattice $E$ to a Banach space $Y$ are those operators which are strictly singular in no closed subspace ge…

A quantitative approach to disjointly non-singular operators

Manuel González, Antonio Martinón

We introduce and study some operational quantities which characterize the disjointly non-singular operators from a Banach lattice $E$ to a Banach space $Y$ when $E$ is order contin…

Disjointly non-singular operators on Banach lattices

Manuel González, Antonio Martí nez-Abejón, Antonio Martinón

An operator $T$ from a Banach lattice $E$ into a Banach space is disjointly non-singular ( $D N$ - $S$ , for short) if no restriction of $T$ to a subspace generated by a disjoint sequen…
