Score breakdown#

Category	Score	One-line note
Writing	7/10	Mostly sentence-case headings.
Math	3/10	Apostrophe transpose throughout; `\cal N`; bare `E`; `i.i.d.`.
Code	8/10	Unicode Greek; pip install at top; PEP8 generally OK; no figsize.
JAX	out of scope	not a JAX lecture.
Figures	4/10	Six `ax.set_title(...)` calls — embedded matplotlib titles violate qe-fig-003.
References	9/10	Citations parenthetical via `{cite}`; no narrative-author misuse.
Links	7/10	One raw markdown link to `python.quantecon.org`; `{doc}` used in 3 places.
Admonitions	N/A	No exercises / proofs.

None found.

[qe-math-002] — Apostrophe ' used as transpose throughout the Riccati derivation. Lines: 81, 94, 108, 114-115, 122, 128, 169, 191, 197, 200, 206-208, 217, 219-220, 225, 231-232. Count: 25+ occurrences.
[qe-fig-003] — Six embedded matplotlib titles via ax.set_title(...). Lines: 488, 550, 619, 660, 682, 716. Captions should be in MyST {figure} blocks, not embedded.

[qe-math-011 (proposed)] — Multivariate normal written as {\cal N}(0,I) (line 180). Style is plain N(0, I).
[qe-writing-009 (proposed)] — i.i.d. used in narrative (line 179). Should be IID.
[qe-math-010 (proposed)] — Bare E used for expectation in display equations (lines 94, 163, 207). Style is \mathbb{E}.
[qe-link-002] — Raw markdown link to python.quantecon.org/markov_perf.html (line 1411); should be {doc} form.
[qe-writing-009 (proposed)] — Smart quotes ’ in narrative (lines 156, 157).

Lecture title in correct Title Case.
H2 headings sentence case (“Overview”, “Review of useful LQ dynamic programming formulas”, “Linked Riccati equations for Markov LQ dynamic programming”, “Applications”, “Example 1”, “Example 2”, “More examples”).
Matrices use bmatrix (13 matrix blocks).
Definitions bolded.
Equation labels and {eq} references used cleanly.
pip install at top; Unicode Greek in code.
No \tag, no align-inside-$$ issues; no figsize, no Title-Case axis labels.

Replace every ' used as transpose with ^\top (highest priority).
Remove the six ax.set_title(...) calls; if a label is needed, use a {figure} block with caption.
Replace {\cal N} with plain N.
Replace i.i.d. with IID.
Replace bare E with \mathbb{E}.
Convert markdown URL to python.quantecon.org/markov_perf.html into a {doc} reference.
