Theorem rdgruledefg 6647
Description: The recursion rule for the recursive definition generator is defined everywhere. (Contributed by Jim Kingdon, 4-Jul-2019.)
Hypothesis
Ref Expression
rdgruledefg.1 𝐹 Fn V
Assertion
Ref Expression
rdgruledefg (𝐴𝑉 → (Fun (𝑔 ∈ V ↦ (𝐴 𝑥 ∈ dom 𝑔(𝐹‘(𝑔𝑥)))) ∧ ((𝑔 ∈ V ↦ (𝐴 𝑥 ∈ dom 𝑔(𝐹‘(𝑔𝑥))))‘𝑓) ∈ V))
Distinct variable groups:   𝐴,𝑔   𝑔,𝑉   𝑥,𝑔,𝐹
Allowed substitution hints:   𝐴(𝑥, 𝑓)   𝐹(𝑓)   𝑉(𝑥, 𝑓)
