Image under a basis map u^k -> P_k A013611
- Concludes
- basis_map_A013611 of Triangle read by rows: T(n,k) is the number of k-matchings in the n-sunlet graph (0 <= k <= n).
- Premises
- Triangle read by rows: T(n,k) is the number of k-matchings in the n-sunlet graph (0 <= k <= n).
sequence: Every row P_n, n >= 0, is zero or real-rooted with all roots in (-inf, 0]
- Triangle read by rows: T(n,k) is the number of k-matchings in the n-sunlet graph (0 <= k <= n).
