Ramseyan variations on symmetric subsequences

Verbitsky, O. (Algebra and Discrete Mathematics, 2003)

A theorem of Dekking in the combinatorics of words implies that there exists an injective order-preserving transformation f : {0, 1, . . . , n} → {0, 1, . . . , 2n} with the restriction f(i + 1) ≤ f(i) + 2 such that for ...
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 ...
