Narrow vein mining — A challenge to the operator
2020Narrow veins represent an important resource of metals throughout the world, however they are generally technically challenging to exploit because of their geologically complex nature. The requirement of the operator is to produce ore with little dilution and within the framework of economic viability and safety.

On two definitions of a narrow operator on Köthe–Bochner spaces
Archiv der Mathematik, 2018Let \((\Omega,\Sigma,\mu)\) be a finite atomless measure space, \(E\) be a Köthe-Banach space over \((\Omega,\Sigma,\mu)\), \(X\) be a Banach space and \(E(X)\) be the corresponding Köthe-Bochner space. Given a Banach space \(Y\), a continuous linear operator \(T : E(X) \to Y\) is called weakly functionally narrow if, for every \(A \in \Sigma\), \(x ...

Narrow Operators on Bochner L???-Spaces
2016Narrow operators on L???(??;X)-spaces are studied. We present a sufficient criterion for such an operator to be narrow that resembles the characterization on narrow operators on L???(??) and show that the criterion is necessary for certain X, e.g., for spaces with the RNP.
