{
  "map": "A013611",
  "operation": "basis_map"
}

Premises

• A convolution triangle of numbers based on A001906 (even-indexed Fibonacci numbers). (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" } } }
• { "claim": "interlacing", "from_index": 1, "kind": "weak", "orientation": "unordered" }

Verification and certificate

• polytool: replayed (the certificate replayed when the step was written)
• Lean: not attempted
• certificate: basis_map, SHA-256 ec9e34cfb3485f22ec3a7084e3f08aa6ab59ecc5732b9f8d77bd4967cb7e7037, 13,345 bytes (2,520 compressed); download JSON
