basis_map A027467 → concludes about Riordan array (1, 3+x). JSON

Theorem

Geometric basis map (elementary) polytool ?

Operation

Image under a basis map u^k -> P_k

{
  "map": "A027467",
  "operation": "basis_map"
}

Premises

• basis-map coefficients of Riordan array (1, 3+x). (sequence)
  uses: Every row P_n, n >= 1, is zero or real-rooted with all roots in (-inf, 15]

Claims

• { "claim": "real_rooted", "from_index": 1, "region": { "upper": { "closed": true, "value": "0" } } }

Verification and certificate

• polytool: replayed (the certificate replayed when the step was written)
• Lean: not attempted
• certificate: basis_map, SHA-256 a2bbf0c5e9e473d180f4e3ad3b5f9c0e44a00a3abf8a2d61be3bb5c209c358f7, 11,704 bytes (2,212 compressed); download JSON
