Definition df-ehl

Description: Define a function generating the real Euclidean spaces of finite dimension. The case n = 0 corresponds to a space of dimension 0, that is, limited to a neutral element (see ehl0 ). Members of this family of spaces are Hilbert spaces, as shown in - ehlhl . (Contributed by Thierry Arnoux, 16-Jun-2019)
