Abstract
In a dual pair 〈E, F〉 one wants to define topologies on E associated with collections of suitable subsets of F. (This generalises the definition of the norm topology on the dual E′ of a Banach space E, in this case for the dual pair 〈E′, E〉.) Such a collection \(\mathcal M\) defines a ‘polar topology’ on E, where the corresponding neighbourhoods of zero in E are polars of the members of \(\mathcal M\). Examples of such topologies are the weak topology and the strong topology. In the first part of the chapter we define polars and investigate some of their properties.
