Do the problem sets and write them up
7–14 weeks (10–12 hrs/week)
Take Algebraic geometry for free and do the problem sets on affine and projective varieties, morphisms and sheaves. Write every solution up in LaTeX and keep the source and the PDF in one public repo as you go.
Proof required
Link your public repo with the LaTeX source and the PDF of the problem sets on affine and projective varieties, morphisms and sheaves, and show your self-check (Self-check without an answer key).
What gets checked
- Every proof is complete and correct.
- Examples are worked on explicit equations.
- Each step names the result it uses.
Common mistakes
- Copying posted solutions: verifiers read the reasoning and the history.
- A proof that skips the hard step.
- Asking for review before the self-check.
Powstik Guide
A public repo with your LaTeX write-ups of the problem sets on affine and projective varieties, morphisms and sheaves.
Steps
- Make a public repo for this course.
- Do one problem set at a time; typeset it in LaTeX and commit.
- Self-check: The course has no answer key. For each problem, name the definition or theorem every step uses; a step you cannot name is a gap. Then swap write-ups with a study partner before you ask for review.
- Fix what the self-check shows, and say what you fixed.
- Ask three people who know the topic to check it.

What a verifier looks for
- Every proof is complete and correct.
- Examples are worked on explicit equations.
- Each step names the result it uses.
- Pick two proofs and check every step: each argument must be correct and complete, not just present.
- Ask about one step; the answer should be clear.

Study one curve in full
1–3 weeks (5–8 hrs/week)
Use what you learned. Make an expository write-up on one plane curve you choose (for example y² = x³ − x): its points, its singular points, its projective closure and its intersections with lines, all proved. Typeset it in LaTeX (or a notebook with LaTeX maths) in your public repo.
Proof required
Link an expository write-up on one plane curve you choose (for example y² = x³ − x): its points, its singular points, its projective closure and its intersections with lines, all proved, in your public repo.
What gets checked
- Every claim is proved.
- Singular points are found correctly.
- The projective closure is computed correctly.
Common mistakes
- A gap in the main argument.
- A result stated but not proved.
Powstik Guide
An expository write-up on one plane curve you choose (for example y² = x³ − x): its points, its singular points, its projective closure and its intersections with lines, all proved.
Steps
- Write one line: what you will prove or show.
- Draft it, then read it cold the next day.
- Ask someone to read it and mark the first step they doubt.
- Fix it and typeset the final version.
- Ask three people to check it.

What gets sent back
- A main step left unproved.
- Not clearly the person's own work.
- Claims more than it proves.
