Abstract

A nearness space is Cauchy complete if every regular Cauchy filter on the space is convergent. We show that the category CCNear 2 of Cauchy complete N 2 spaces is reflective in the category Near 2 C of N 2-spaces and Cauchy maps and that the reflection of an N 2-space is given by the strict extension associated with regular Cauchy filters on the space.
