Reference fixed to Second Edition. Next step will be to fix presentation of the citations, and complete the proofs where missing. &mdash; Lord_Farin (talk) 16:47, 22 September 2022 (UTC)

Up to $I.1.7$. Quite more work this time around due to increased rigour all around. &mdash; Lord_Farin (talk) 18:10, 12 October 2022 (UTC)

Up to $I.2.6$. Some nice improvements of the flow. &mdash; Lord_Farin (talk) 19:08, 14 October 2022 (UTC)

Finished $I.2$. &mdash; Lord_Farin (talk) 07:16, 25 October 2022 (UTC)

Finished $I.3$. &mdash; Lord_Farin (talk) 07:04, 29 October 2022 (UTC)

Refactorings due

 * Strict analysis of where complete subfields of $\C$ are required, plus supplemental material that a complete subfield of $\C$ is either $\R$ or $\C$.
 * Definition:Linear Subspace vs Definition:Closed Linear Subspace, in the flow after Definition:Orthogonal Projection
 * The categories around linear functionals/transformations are a complete mess

Skipped thus far (that is, what needs to be done still)

 * $I.1.8$ Absolutely continuous complex functions
 * $I.1.10-13: $ Bergman Spaces $L^2_a(G)$
 * $I.2.10$ Proof of Double Orthocomplement is Closed Linear Span, which needs some of the exercises
 * $I.3$ Exercises 3,4 about power series (after Riesz Representation Theorem (Hilbert Spaces)/Examples/Space of Square Summable Mappings)
 * $I.3$ Exercise 5 about $I.1.8$ (see above)
 * $I.3$ Exercise 6 evaluation of derivative at point is not bounded
 * $I.4.2$ Proof of Orthonormal Subset of Hilbert Space Extends to Basis using Zorn's Lemma
 * $I.5.6-11:$ Rigorous foundations of Fourier analysis and $L^2_\C[0,2\pi]$.
 * $II.1.5:$ Bounded functions induce bounded linear operators on $L^2(\mu)$.
 * $II.1.6:$ Integral operators with certain kernels are bounded linear operators.
 * Maybe some more of $II.1 \text{ Exercises}, II.2 \text{ Exercises}$.
 * $II.2.8,9:$ Examples which are useful but their basis hasn't been covered.
 * $II.2.10:$ Unilateral shift on $\ell^2(\N)$
 * $II.4.7-8$: Integral operators with certain kernels are compact operators
 * $II.6$: Sturm-Liouville theory
