Branch focus:

• Foundations and First Proofs covers rigorous single/multivariable calculus with plentiful exercises and worked solutions.
• Core Real Analysis develops abstract sequences, topology, and measure-ready theorems (Tao, Rudin, Royden-Fitzpatrick).
• Measure Theory and Integration deepens Lebesgue/Differentiation techniques, setting up modern analysis.
• Princeton Lectures align per volume (Fourier, Complex, Real, Functional) and dovetail with Tao and Brezis for cross-references.
• Functional Analysis and PDE Interfaces connect Banach/Hilbert frameworks with Sobolev/PDE applications, ideal after the measure tier.

Suggested Learning Paths

1. Foundations → Real Analysis Core → Measure Theory

   • Start with Wade (text plus solutions) to build comfort with proofs.
   • Follow with Marsden & Hoffman for multivariable rigor.
   • Move into Tao Analysis I & II, then reinforce abstraction via Rudin or Royden–Fitzpatrick.
   • Transition to Lebesgue theory with Tao’s Introduction to Measure Theory and Wheeden–Zygmund for deeper applications.

2. Measure Theory → Functional Analysis → PDE Applications

   • After the measure texts above, read Buhler & Salamon’s ETH notes for a quick functional analysis foundation.
   • Proceed to Stein & Shakarchi Vol. 4 for operator-focused analysis.
   • Capstone with Brezis to connect functional analysis to Sobolev spaces and partial differential equations.

3. Princeton Lectures in Analysis Track

   • Use the Vol. 1–4 collection for the full program (Fourier, Complex, Real, Functional).
   • Pair the physical Vol. 3 and Vol. 4 files for quick access to those topics.
   • Integrate related references: Tao Analysis I/II align with Vol. 3, and Brezis/Wheeden serve as advanced companions once the Princeton sequence is complete.

4. Author-Centric Tao Route

   • Work through Analysis I → Analysis II → Introduction to Measure Theory.
   • Supplement with Rudin for alternate presentations and Stein & Shakarchi Vol. 4 for functional analysis continuity.

5. (My Path) Zygmund-First Route

   • This mirrors my actual study flow: start from Wheeden & Zygmund - Measure and Integral and fan out both backward and forward.
   • Backfill any missing foundations by dipping into Tao Analysis I/II or Rudin whenever topology/sequence results are needed.
   • Extend forward toward functional analysis and PDE texts (Buhler & Salamon, Stein & Shakarchi Vol. 4, Brezis) so the measure insights connect with operator theory and Sobolev applications.
