Research Interests




My mathematical research is almost entirely concerned with vector lattices (also known as Riesz spaces), Banach lattices and operators on them. In recent years I have increasingly concentrated on the order structure of spaces of linear operators between two Banach lattices and the relationship between various spaces. Typical questions I have investigated are when the space of regular operators (i.e. those which are the difference of two positive operators) is a lattice or when it coincides with the space of all bounded operators. A further strand concerns domination properties which ask when a positive operator must inherit some desirable property which is possessed by a positive operator which dominates it.
