Description: The covers relation for a left vector space (or a left module). (cvbr2 30645 analog.) (Contributed by NM, 9-Jan-2015.)

Hypotheses

Ref	Expression
lcvfbr.s	⊢ 𝑆 = (LSubSp‘𝑊)
lcvfbr.c	⊢ 𝐶 = ( ⋖L ‘𝑊)
lcvfbr.w	⊢ (𝜑 → 𝑊 ∈ 𝑋)
lcvfbr.t	⊢ (𝜑 → 𝑇 ∈ 𝑆)
lcvfbr.u	⊢ (𝜑 → 𝑈 ∈ 𝑆)

Assertion

Ref	Expression
lcvbr2	⊢ (𝜑 → (𝑇𝐶𝑈 ↔ (𝑇 ⊊ 𝑈 ∧ ∀𝑠 ∈ 𝑆 ((𝑇 ⊊ 𝑠 ∧ 𝑠 ⊆ 𝑈) → 𝑠 = 𝑈))))
