Distinct variable groups:   𝑡,𝑗,𝐾   𝑡,𝑊   𝑡,𝑂   𝑅,𝑗   𝑗,𝑊   𝑗,𝑋,𝑡   𝑗,𝑌,𝑡

Allowed substitution hints:   𝜑(𝑡, 𝑗)   𝐴(𝑡, 𝑗)   + (𝑡, 𝑗)   𝑅(𝑡)   𝑆(𝑡, 𝑗)   · (𝑡, 𝑗)   𝑈(𝑡, 𝑗)   𝐻(𝑡, 𝑗)   𝑀(𝑡, 𝑗)   𝑂(𝑗)   𝑉(𝑡, 𝑗)   0 (𝑡, 𝑗)

Proof of Theorem hvmapvalvalN

Dummy variable 𝑦 is distinct from all other variables.
