Theorem ress0g 13704
Description: 0g is unaffected by restriction. This is a bit more generic than submnd0 13705. (Contributed by Thierry Arnoux, 23-Oct-2017.)
Hypotheses
Ref Expression
ress0g.s 𝑆 = (𝑅s 𝐴)
ress0g.b 𝐵 = (Base‘𝑅)
ress0g.0 0 = (0g𝑅)
Assertion
Ref Expression
ress0g ((𝑅 ∈ Mnd ∧ 0𝐴𝐴𝐵) → 0 = (0g𝑆))

Proof of Theorem ress0g
Dummy variable 𝑥 is distinct from all other variables.
