  • Binary coronas of balleans 
    Protasov, I.V. (Algebra and Discrete Mathematics, 2003)
    A ballean B is a set X endowed with some family of subsets of X which are called the balls. We postulate the properties of the family of balls in such a way that a ballean can be considered as an asymptotic counterpart ...
  • Uniform ball structures 
    Protasov, I.V. (Algebra and Discrete Mathematics, 2003)
    A ball structure is a triple B = (X, P, B), where X, P are nonempty sets and, for all x ∈ X, α ∈ P, B(x, α) is a subset of X, x ∈ B(x, α), which is called a ball of radius α around x. We introduce the class of uniform ...
