English
Λ is the meromorphic function obtained by subtracting the simple poles 1/s f0 and ε/(k−s) g0 from Λ₀; this aligns Λ with the Mellin transform in the presence of the pole corrections.

Λ — полуприводимая функция, равная Λ₀ минус простые полюса; т.е. Λ(s) = Λ₀(s) − (1/s) f0 − (ε/(k−s)) g0.

$$Λ(s) := Λ₀(s) − (1 / s) • f₀ − (ε / (k − s)) • g₀$$
