quasimeasure

plural quasimeasures

1. mathematicsA nonnegative increasing semiadditive set function defined on a ring of sets that is continuous above the origin and takes its values in the extended domain of real numbers.

   Motivated by the Arzel\`a-Ascoli theorem for Cᵇ(X,E), where X is an^([sic]) Euclidean space and E an arbitrary Banach space, we construct a quasimeasure for this space and study its properties.

2. An imprecise means of measuring something.

   Performative regimes (see Power, 1997, 2004; Strathern, 2000) in many countries now judge the worth of an academic by the number of their publications, or through some quasimeasure of quality such as download data or citations for the paper.
