Theorem pridlval 39010

Description: Obsolete theorem, use prmidlval 21618 instead. The class of prime ideals of a ring 𝑅. (Contributed by Jeff Madsen, 10-Jun-2010.) (Proof modification is discouraged.) (New usage is discouraged.)

Hypotheses

Ref	Expression
pridlval.1	⊢ 𝐺 = (1st ‘𝑅)
pridlval.2	⊢ 𝐻 = (2nd ‘𝑅)
pridlval.3	⊢ 𝑋 = ran 𝐺

Assertion

Ref	Expression
pridlval	⊢ (𝑅 ∈ RingOps → (PrIdl‘𝑅) = {𝑖 ∈ (Idl‘𝑅) ∣ (𝑖 ≠ 𝑋 ∧ ∀𝑎 ∈ (Idl‘𝑅)∀𝑏 ∈ (Idl‘𝑅)(∀𝑥 ∈ 𝑎 ∀𝑦 ∈ 𝑏 (𝑥𝐻𝑦) ∈ 𝑖 → (𝑎 ⊆ 𝑖 ∨ 𝑏 ⊆ 𝑖)))})

Distinct variable groups:   𝑅,𝑖,𝑥,𝑦,𝑎,𝑏   𝑖,𝑋   𝑖,𝐻

Allowed substitution hints:   𝐺(𝑥, 𝑦, 𝑖, 𝑎, 𝑏)   𝐻(𝑥, 𝑦, 𝑎, 𝑏)   𝑋(𝑥, 𝑦, 𝑎, 𝑏)

Proof of Theorem pridlval

Dummy variable 𝑟 is distinct from all other variables.
