where formula_195 means the space of all linear continuous functionals formula_196 endowed with the "topology of uniform convergence on totally bounded sets" in formula_197 (and formula_198 means the dual to formula_195 in the same sense). The spaces of this class are called stereotype spaces, and the corresponding theory found a series of applications in Functional analysis and Geometry, including the generalization of Pontryagin duality for non-commutative topological groups.
