Abstract
I will first introduce operator-valued Schur multipliers and provide a Grothendieck-type characterisation of such multipliers. Then I will give an affirmative solution to the positive extension problem for a partially defined operator-valued multiplier φ in terms of a relation between the canonical and maximal dual operator system structures associated with the domain of φ.
