Description: Membership in a centralizer. (Contributed by Stefan O'Rear, 6-Sep-2015.)
Hypotheses
Ref Expression
cntzfval.b 𝐵 = (Base‘𝑀)
cntzfval.p + = (+g𝑀)
cntzfval.z 𝑍 = (Cntz‘𝑀)
Assertion
Ref Expression
cntzel ((𝑆𝐵𝑋𝐵) → (𝑋 ∈ (𝑍𝑆) ↔ ∀𝑦𝑆 (𝑋 + 𝑦) = (𝑦 + 𝑋)))
Distinct variable groups:   𝑦, +   𝑦,𝑀   𝑦,𝑆   𝑦,𝑋
Allowed substitution hints:   𝐵(𝑦)   𝑍(𝑦)
