Description: The predicate "is an atom". (ela 30110 analog.) (Contributed by NM, 18-Sep-2011.)

Hypotheses

Ref	Expression
isatom.b	⊢ 𝐵 = (Base‘𝐾)
isatom.z	⊢ 0 = (0.‘𝐾)
isatom.c	⊢ 𝐶 = ( ⋖ ‘𝐾)
isatom.a	⊢ 𝐴 = (Atoms‘𝐾)

Assertion

Ref	Expression
isat	⊢ (𝐾 ∈ 𝐷 → (𝑃 ∈ 𝐴 ↔ (𝑃 ∈ 𝐵 ∧ 0 𝐶𝑃)))

Proof of Theorem isat

Dummy variable 𝑥 is distinct from all other variables.
