📝 Translation Quality

Criterion	Score
Accuracy	9/10
Fluency	8/10
Terminology	9/10
Formatting	10/10
Overall	8.9/10

Summary: The translation of the changed sections (Vector Spaces, Basic Properties, Applications in Economics x2, Matrix Operations, Eigenvalues and Eigenvectors) is highly accurate, fluent, and terminologically consistent with the glossary and style policy. Technical terms are correctly retained in English with appropriate Malayalam case-suffixes, the hortative register is used correctly for instructional actions, and all code/math blocks are preserved intact with no syntax errors. Minor stylistic improvements are possible (e.g., splitting a few longer compound sentences for better classroom readability), but no accuracy, terminology, or formatting issues were found in the modified sections. Consistent and correct application of the light-verb pattern (e.g., 'satisfy ചെയ്യുന്നു', 'represent ചെയ്യുന്നു', 'demonstrate ചെയ്യാം') across all changed sections Technical terms (vector space, matrix, eigenvalue, eigenvector, Leontief inverse, Markov chain) are correctly preserved in English per the glossary and policy Mathematical notation, LaTeX blocks, and code cells are preserved exactly without alteration, and code comments remain untranslated as required Hortative classroom register ('നമുക്ക് ... ചെയ്യാം') is correctly and consistently applied in invitations to compute/visualize Comma placement after fronted topic phrases and before colons introducing code/equations follows the style guide accurately

Suggestions:

• [minor · fluency] lecture.md — ### Basic Properties: The sentence 'ഈ properties, mathematical operations-ന് കീഴിൽ vector spaces പ്രവചനീയമായി പെരുമാറുന്നു എന്ന് ഉറപ്പാക്കുന്നു' is missing the perfect-stative or completive construction consistency check, but more importantly reads slightly awkward with 'പ്രവചനീയമായി പെരുമാറുന്നു' as a nested clause; a comma after the fronted topic phrase 'ഈ properties,' is correctly present, which is good, but the se… → ഈ properties, mathematical operations-ന് കീഴിൽ vector spaces പ്രവചനീയമായി പെരുമാറുന്നു എന്ന് ഉറപ്പാക്കുന്നു. ഇത് economic choice sets represent ചെയ്യാൻ അവയെ അനുയോജ്യമാക്കുന്നു.
• [minor · terminology] lecture.md — ## Matrix Operations: The word 'compose' was translated as 'compose ചെയ്യാൻ' which is consistent with the light-verb pattern used throughout, but 'efficiently' was dropped from direct translation and merged as 'കാര്യക്ഷമമായി' — this is accurate, not an issue; included only to confirm no loss of meaning. No actual error found; this entry can be disregarded.
• [nit · fluency] lecture.md — #### Applications in Economics (Vector Spaces): The clause 'inverses-ന്റെ നിലനിൽപ്പ് debts, obligations എന്നിവ model ചെയ്യാൻ നമ്മെ അനുവദിക്കുന്നു' drops the coordinating comma convention between 'debts' and 'obligations' before 'എന്നിവ', which is acceptable here since എന്നിവ already functions as the coordinator per policy (coordinated items take എന്നിവ, not -ഉം...-ഉം), so this is correctly handled — flagging only as a nit to confirm no further…

🟢 Approval recommended

The sync metadata is internally consistent and verified (section-count matches the three level-2 headings, source-sha and model match the PR metadata, and the date is valid), with no objective issues in the mechanical translation update.

What changed in this PR

This is an automated translation-sync PR generated by the QuantEcon translation action. It propagates an upstream English lecture update (source PR #985) into the Malayalam (ml) target repository, refreshing the machine translation of lecture.md and recording the sync state so future syncs can detect drift. It fits into the repo's translation-tracking workflow where .translate/state/*.yml files capture the source commit and structural metadata for each translated document.

Changes:

• Expands the Malayalam lecture.md translation with the newly added source content (extra vector-space property, enriched matrix/eigenvalue applications, and an added bullet list on eigenvalue uses).
• Adds a new sync-state file .translate/state/lecture.md.yml recording the source SHA, sync date, model, mode, section count, and tool version.

File	Description
lecture.md	Updates the Malayalam translation paragraphs/bullets to match the upstream English source revisions.
.translate/​state/​lecture.md.yml	New state file recording sync metadata (source-sha, synced-at, model, mode: UPDATE, section-count: 3, tool-version).

I verified the metadata against the PR contents: source-sha matches the sourceCommitSha in the sync metadata, synced-at (2026-10-09) is today's date in the expected YYYY-MM-DD format, mode: UPDATE is consistent with lecture.md being modified, and section-count: 3 correctly matches the three level-2 (## ) headings (Vector Spaces, Matrix Operations, Eigenvalues and Eigenvectors). No objective issues were found.
