Theorem shatomistici 32432

Description: The lattice of Hilbert subspaces is atomistic, i.e. any element is the supremum of its atoms. Part of proof of Theorem 16.9 of [MaedaMaeda] p. 70. (Contributed by NM, 26-Nov-2004.) (New usage is discouraged.)

**Hypothesis**
Ref	Expression
shatomistic.1	⊢ 𝐴 ∈ S_ℋ

**Assertion**
Ref	Expression
shatomistici	⊢ 𝐴 = (span‘∪ {𝑥 ∈ HAtoms ∣ 𝑥 ⊆ 𝐴})

Distinct variable group: 𝑥,𝐴

Proof of Theorem shatomistici Dummy variable 𝑦 is distinct from all other variables.
