Theorem iswomni0 14719

Description: Weak omniscience stated in terms of equality with 0. Like iswomninn 14718 but with zero in place of one. (Contributed by Jim Kingdon, 24-Jul-2024.)

**Assertion**
Ref	Expression
iswomni0	⊢ (𝐴 ∈ 𝑉 → (𝐴 ∈ WOmni ↔ ∀𝑓 ∈ ({0, 1} ↑_𝑚 𝐴)DECID ∀𝑥 ∈ 𝐴 (𝑓‘𝑥) = 0))

Distinct variable groups: 𝐴,𝑓,𝑥 𝑓,𝑉,𝑥

Proof of Theorem iswomni0 Dummy variables 𝑔 𝑧 are mutually distinct and distinct from all other variables.
