Finish abstract linear algebra
Think of the spectral theorem as the point where algebra and geometry become a single language.
A lifelong mathematical education
A self-directed roadmap from rigorous undergraduate mathematics to the foundations of graduate research, designed around clarity, insight, and the beauty of ideas.
This is a garden, not a race. The order of the core subjects matters; the pace is my own.
My starting point is already proof-based: real analysis through Abbott, abstract linear algebra through Axler, and multivariable analysis through Shurman.
Starting snapshot: Axler chapters 1–5 completed; approximately one third of Shurman completed. The checkboxes below mark future reading goals and are saved only in this browser; they do not update public GitHub content.

Core · Algebra
Think of the spectral theorem as the point where algebra and geometry become a single language.
Core · Analysis
The inverse function theorem and generalized Stokes’ theorem will pay dividends throughout geometry and analysis.
Core · Structure and symmetry
Use Artin for its geometric viewpoint.
Core · Spaces and continuity
Core · Analysis and geometry
The remarkable rigidity of complex differentiability makes this a particularly rewarding subject.
Core · Change over time
Think of an ODE as defining a flow, not just something that must be solved.
Companion · Arithmetic
Excellent alongside abstract algebra and often full of pleasant surprises.
Companion · Randomness
Harvard Stat 110 has lectures and extensive self-study resources.
Analysis
Return to Axler’s lucid style, this time with graduate-level analysis.
Geometry
Analysis
Finite-dimensional linear algebra grows into infinite-dimensional geometry.
Topology
Use algebraic invariants to distinguish spaces.
Analysis and mathematical physics
At this level, textbooks overlap and the subject boundaries start to dissolve. Use one main book per area; keep the denser texts for problem sets and reference.
Abstract algebra
Groups, fields, modules, representations and commutative algebra.
Real analysis
Continue into advanced integration, Hilbert spaces and functional analysis.
Complex analysis
Build fluency in analytic continuation, normal families, conformal mapping and residues.
Differential geometry
Topology
Continue through homology, cohomology, duality and CW complexes.
Algebraic geometry
These side paths are not distractions. They keep the larger education playful, broad and full of connections. Begin them when the necessary foundations are in place.

There is no single universal American mathematics PhD entrance exam. Preliminary and qualifying exam syllabi differ by university. Build depth first; use old examinations later to diagnose gaps and practice constructing proofs under constraints.
First benchmark
Use Berkeley’s mathematics preliminary exam resources to test the analysis and algebra foundations.
Advanced benchmark
Use Stanford’s qualifying exam information and Harvard’s graduate qualifying exams as broad targets. Check each department’s current syllabus and links before planning exam-style drills.
Sequence: Try selected problems untimed, identify missing theory, return to textbook exercises, and only then attempt full timed papers. The aim is understanding—not just speed.
At a hobbyist pace of approximately 8–10 hours per week, this roadmap is a multi-year project. A reasonable planning horizon is five to eight years or longer; the exact pace is less important than steady, joyful work.
| Activity | Weekly time | Why |
|---|---|---|
|
Read and reconstruct proofs |
3 hours |
Develop insight and mathematical taste. |

Solve exercises |
4 hours |
Turn passive understanding into real skill. |

Explore a side subject |
1 hour |
Keep the journey broad and enjoyable. |
For each important theorem, ask what its assumptions mean, find an example and a counterexample, and try to recover the proof several days later.
The most rewarding mathematical moments are often the ones where two ideas, once thought unrelated, suddenly turn out to be the same idea in different languages.
