§24.14(i) Quadratic Recurrence Relations

24.14.1 ∑k=0n(nk)⁢Bk⁡(x)⁢Bn−k⁡(y) =n⁢(x+y−1)⁢Bn−1⁡(x+y)−(n−1)⁢Bn⁡(x+y),
24.14.2 ∑k=0n(nk)⁢Bk⁢Bn−k =(1−n)⁢Bn−n⁢Bn−1.
24.14.3 ∑k=0n(nk)⁢Ek⁡(h)⁢En−k⁡(x) =2⁢(En+1⁡(x+h)−(x+h−1)⁢En⁡(x+h)),
24.14.4 ∑k=0n(nk)⁢Ek⁢En−k =−2n+1⁢En+1⁡(0)=−2n+2⁢(1−2n+2)⁢Bn+2n+2.
24.14.5 ∑k=0n(nk)⁢Ek⁡(h)⁢Bn−k⁡(x) =2n⁢Bn⁡(12⁢(x+h)),
24.14.6 ∑k=0n(nk)⁢2k⁢Bk⁢En−k =2⁢(1−2n−1)⁢Bn−n⁢En−1.

Let m+n be even with m and n nonzero. Then

§24.14(ii) Higher-Order Recurrence Relations

In the following two identities, valid for n≥2, the sums are taken over all nonnegative integers j,k,ℓ with j+k+ℓ=n.

24.14.8 ∑(2⁢n)!(2⁢j)!⁢(2⁢k)!⁢(2⁢ℓ)!⁢B2⁢j⁢B2⁢k⁢B2⁢ℓ =(n−1)⁢(2⁢n−1)⁢B2⁢n+n⁢(n−12)⁢B2⁢n−2,
24.14.9 ∑(2⁢n)!(2⁢j)!⁢(2⁢k)!⁢(2⁢ℓ)!⁢E2⁢j⁢E2⁢k⁢E2⁢ℓ =12⁢(E2⁢n−E2⁢n+2).

In the next identity, valid for n≥4, the sum is taken over all positive integers j,k,ℓ,m with j+k+ℓ+m=n.

24.14.10 ∑(2⁢n)!(2⁢j)!⁢(2⁢k)!⁢(2⁢ℓ)!⁢(2⁢m)!⁢B2⁢j⁢B2⁢k⁢B2⁢ℓ⁢B2⁢m=−(2⁢n+33)⁢B2⁢n−43⁢n2⁢(2⁢n−1)⁢B2⁢n−2.

For (24.14.11) and (24.14.12), see Al-Salam and Carlitz (1959). These identities can be regarded as higher-order recurrences. Let det[ar+s] denote a Hankel (or persymmetric) determinant, that is, an (n+1)×(n+1) determinant with element ar+s in row r and column s for r,s=0,1,…,n. Then

24.14.11 det[Br+s] =(−1)n⁢(n+1)/2⁢(∏k=1nk!)6/(∏k=12⁢n+1k!),
24.14.12 det[Er+s] =(−1)n⁢(n+1)/2⁢(∏k=1nk!)2.
