- W2784967900 abstract "A ball structure is a triple B = (X, P,B), whereX, P are nonempty sets and, for all x ∈ X, ® ∈ P, B(x, ®) is a subsetof X, x ∈ B(x, ®), which is called a ball of radius ® around x.We introduce the class of uniform ball structures as an asymptoticcounterpart of the class of uniform topological spaces. We showthat every uniform ball structure can be approximated by metrizableball structures. We also define two types of ball structuresclosed to being metrizable, and describe the extremal elements inthe classes of ball structures with fixed support X." @default.
