From b5f0566da573bdccc03c226689617f3061558d71 Mon Sep 17 00:00:00 2001 From: Matt McKay Date: Fri, 24 Jul 2026 11:46:52 +1000 Subject: [PATCH] Remove three duplicate bibliography entries so the .bib parses at all MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pybtex refuses to parse a bibliography containing a repeated key, and this file has carried three of them — GilboaSchmeidler:1989, Whittle_1981 and Whittle_1990 each appear twice, once indented in the main body and once unindented near the end. The two copies of each are byte-identical apart from leading whitespace. The effect is total rather than local: `parse_file` raises `BibliographyDataError: repeated bibliography entry` and no bibliography is built, so *every* {cite} in the edition fails to resolve. That is what the "could not find bibtex key" warnings on #202 actually are — the keys are present in the file, but nothing ever parsed it. The 70 entries backfilled in #203 were correct and could never have taken effect while this stood. Predates #203: the same three duplicates and the same parse error are present at 693aa63, before that PR. Verified: pybtex now parses 480 entries, and all 61 keys the #202 build reported missing resolve, as do the three formerly-duplicated ones. Removes the later copy of each; the earlier copy in the main body is kept. --- lectures/_static/quant-econ.bib | 37 --------------------------------- 1 file changed, 37 deletions(-) diff --git a/lectures/_static/quant-econ.bib b/lectures/_static/quant-econ.bib index d5b7afc..6c7f069 100644 --- a/lectures/_static/quant-econ.bib +++ b/lectures/_static/quant-econ.bib @@ -4104,43 +4104,6 @@ @article{Campbell1987 pages = {1249--1273}, year = {1987} } - -@article{GilboaSchmeidler:1989, - author = {Gilboa, Itzhak and Schmeidler, David}, - date-added = {2020-08-10 09:11:02 -0500}, - date-modified = {2020-08-10 09:11:02 -0500}, - journal = {Journal of Mathematical Economics}, - keywords = {climate,modeling}, - mendeley-groups = {nsfbib}, - month = {apr}, - number = {2}, - pages = {141--153}, - title = {{Maxmin Expected Utility with Non-Unique Prior}}, - volume = {18}, - year = {1989} -} - -@article{Whittle_1981, - author = {Peter Whittle}, - year = {1981}, - title = {Risk-Sensitive Linear/Quadratic/Gaussian Control}, - journal = {Advances in Applied Probability}, - volume = {13}, - number = {4}, - pages = {764-777} -} - -@book{Whittle_1990, - author = {Peter Whittle}, - title = {Risk-Sensitive Optimal Control}, - year = {1990}, - publisher = {Wiley}, - address = {New York} -} - - - - % --------------------------------------------------------------------------- % Entries synced from QuantEcon/lecture-python.myst lectures/_static/quant-econ.bib % on 2026-07-24.
