SENGUPTA, Z.T. ZHUKOVSKAYA, S.E. ZHUKOVSKIY Proof Take arbitrary points x ∈ X, y ∈ Y, yψ ∈ Ψ(x), yφ ∈ Φ(x) and a number ε > 0 such that ρY (yψ, y) < dist(Ψ(x), y) + ε 2 , ρY (y, yφ) < dist(y,Φ(x)) A function ρX : X ×X → R+ is called a (q1, q2)-quasimetric if • ρX(x, y) = 0⇔ x = y ∀ x, y ∈ X (the identity axiom); • ρX(x, z) ≤ q1ρX(x, y) +	cache/ijassa-854.pdf	txt/ijassa-854.txt
