Theorem hgmapval 42694

Description: Value of map from the scalar division ring of the vector space to the scalar division ring of its closed kernel dual. Function sigma of scalar f in part 14 of [Baer] p. 50 line 4. TODO: variable names are inherited from older version. Maybe make more consistent with hdmap14lem15 42689. (Contributed by NM, 25-Mar-2015.)

Distinct variable groups:   𝑦,𝑣,𝐾   𝑣,𝐵,𝑦   𝑣,𝑀,𝑦   𝑣,𝑈,𝑦   𝑣,𝑉   𝑣,𝑊,𝑦   𝑣,𝑋,𝑦

Allowed substitution hints:   𝜑(𝑦, 𝑣)   𝐶(𝑦, 𝑣)   𝑅(𝑦, 𝑣)   ∙ (𝑦, 𝑣)   · (𝑦, 𝑣)   𝐻(𝑦, 𝑣)   𝐼(𝑦, 𝑣)   𝑉(𝑦)   𝑌(𝑦, 𝑣)

Proof of Theorem hgmapval

Dummy variable 𝑥 is distinct from all other variables.
