Definition df-bj-rvec 37965

Description: Definition of the class of real vector spaces. The previous definition, ⊢ ℝ-Vec = {𝑥 ∈ LMod ∣ (Scalar‘𝑥) = ℝ_fld}, can be recovered using bj-isrvec 37966. The present one is preferred since it does not use any dummy variable. That ℝ-Vec could be defined with LVec in place of LMod is a consequence of bj-isrvec2 37972. (Contributed by BJ, 9-Jun-2019.)
