Mem resolvent Set of range eq top

LinearPMap.IsSelfAdjoint.mem_resolventSet_of_range_eq_top

Plain-language statement

(T - z • 1).range = ⊤ is a sufficient condition for z ∈ ρ T (and it is a necessary condition by definition of ρ).

Unitary Conj is Self Adjoint

LinearPMap.unitaryConj_isSelfAdjoint

Plain-language statement

Unitary conjugation preserves self-adjointness: if A is a self-adjoint operator on H and u : H ≃ₗᵢ[ℂ] H' is unitary, then u A u⁻¹ is self-adjoint on H'. Symmetry, dense domain, and the two deficiency surjectivities of A all transfer through u.
