Theorem

Geometric basis map (elementary) polytool ?

Operation

Image under a basis map u^k -> P_k

  "map": "A013609",
  "operation": "basis_map"
}

Premises

• basis-map coefficients of Irregular triangle read by rows formed by taking every other row of the Delannoy array (A008288) regarded as a tr… (sequence)
  uses: Every row P_n, n >= 0, is zero or real-rooted with all roots in (-inf, 0]
