Triple

Target class: property of uniform spaces
Context triple: [Cauchy completeness, instanceOf, property of uniform spaces]

• A. complete metric space chosen
  A complete metric space is a metric space in which every Cauchy sequence converges to a limit that lies within the space.
• B. pseudometric
  A pseudometric is a function that assigns a nonnegative real number as a "distance" between any two points in a set, satisfying all the axioms of a metric except that distinct points are allowed to have zero distance.
• C. nuclear space
  A nuclear space is a topological vector space in which every continuous linear map into an arbitrary Banach space is nuclear (i.e., can be approximated by finite-rank operators with rapidly decaying singular values), giving it strong compactness and approximation properties.
• D. locally convex space
  A locally convex space is a topological vector space whose topology is generated by a family of seminorms, so that every point has a neighborhood base consisting of convex sets.
• E. criterion for uniform convergence
  A criterion for uniform convergence is a condition or set of conditions that allows one to determine whether a sequence (or series) of functions converges uniformly to a limiting function on a given domain.
• F. None of above.
