basis_map A007318 → concludes about Triangle whose (i,j)-th entry is binomial(i,j)*10^(i-j)*1^j. JSON

Theorem

Geometric basis map (elementary) polytool ?

Operation

Image under a basis map u^k -> P_k

{
  "map": "A007318",
  "operation": "basis_map"
}

Premises

• Triangle whose (i,j)-th entry is binomial(i,j)*9^(i-j)*1^j. (sequence)
  uses: Every row P_n, n >= 0, is zero or real-rooted with all roots in (-inf, 0]

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 54c6def9da39e71c6d619e5c4c1a39248753e699cf8291ad435a6ba8323fef0d, 6,857 bytes (1,385 compressed); download JSON
