Mackey space

A Mackey space, named after George W. Mackey, is a concept in the field of functional analysis, particularly in relation to topological vector spaces. It is primarily defined in the context of locally convex spaces and functional analysis. A locally convex space \( X \) is called a Mackey space if the weak topology induced by its dual space \( X' \) (the space of continuous linear functionals on \( X \)) coincides with its original topology.
