Theorem ssmxidl 31621
Description: Let 𝑅 be a ring, and let 𝐼 be a proper ideal of 𝑅. Then there is a maximal ideal of 𝑅 containing 𝐼. (Contributed by Thierry Arnoux, 10-Apr-2024.)
Hypothesis
Ref Expression
ssmxidl.1 𝐵 = (Base‘𝑅)
Assertion
Ref Expression
ssmxidl ((𝑅 ∈ Ring ∧ 𝐼 ∈ (LIdeal‘𝑅) ∧ 𝐼𝐵) → ∃𝑚 ∈ (MaxIdeal‘𝑅)𝐼𝑚)
Distinct variable groups:   𝐵,𝑚   𝑚,𝐼   𝑅,𝑚

Proof of Theorem ssmxidl
Dummy variables 𝑗 𝑝 𝑧 𝑘 are mutually distinct and distinct from all other variables.
