𝐪^κ_{m,n,r}, e.q.mnr.def (3239-3250), by the explicit recursion that solves the
characterization: q_{n,0} = 𝐣_n - ⟨⟨𝐣_n⟩⟩, q_{n,r+1}(t) = -∫_0^t q_{n,r} + ⟨⟨∫_0^· q_{n,r}⟩⟩
(so ∂_t q_{r+1} = -q_r and ⟨⟨q_{r+1}⟩⟩ = 0, ⟨⟨·⟩⟩ = ∫_0^1). The index r ranges over ℕ₀
and q is
4τ_m-periodic (not τ_m-periodic); see qMNR_char.
