Theorem

Geometric basis map (elementary) polytool ?

Operation

Image under a basis map u^k -> P_k

{
  "map": "A038255",
  "operation": "basis_map"
}

Premises

• basis-map coefficients of A Jacobsthal triangle. (sequence)
  uses: Every row P_n, n >= 0, is zero or real-rooted with all roots in (-inf, 6]

Claims

• { "claim": "real_rooted", "from_index": 0, "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 bfcb1dd07376e7ae9dff214de38fffcfd30b86e1b84fd4f6388d2c708897e927, 11,673 bytes (2,203 compressed); download JSON
