WebApr 4, 2024 · The Buchstab function is the unique continuous function w: R ≥ 1 → R > 0 defined by the delay differential equation u w ( u) = 1 ( 1 ≤ u ≤ 2), ( u w ( u)) ′ = w ( u − 1) ( u > 2) ( Panario, 1998 ). It approaches the asymptotic value w ( u) → e − γ ≈ 0.561459 as u → ∞ (and in fact has nearly reached this value already by u ≈ 4 ). • Buchstab function, a function used similarly to estimate the number of rough numbers, whose convergence to is controlled by the Dickman function • Golomb–Dickman constant
