dc.description.abstract	Given ε > 0, a continuous linear functional φ on C(X) is said to be ε-disjointness preserving if \|φ(f)φ(g)\| ≤ ε whenever f,g ∈ C(X) satisfy ∥f∥∞ = ∥g∥∞ = 1 and fg ≡ 0. In this paper we provide the exact maximal distance from ε-disjointness preserving linear functionals to the set of weighted point evaluation functionals.
