Math Books

This repo includes some info on cropping / formatting math PDF books for reading on Phone / ebook reader type of devices.

Milne's Course Notes PDF for Phone

The author of Group theory and field and Galois theory book (course notes) from https://www.jmilne.org/math/CourseNotes/ has published the tex files, so I made some formatting change and generated PDFs for Phones and Kindle. All the credit and goes to the original author. I might have introduced formatting problems, so please check the official PDF if you encounter one.

• Group Theory
• Field and Galois Theory

The following adjustments are made:

• PDF size adjusted for phone screen
• Adjusted font to be more like sans-serif, for screen reading
• Shrank some diagrams
• Long formulas were broke into multiple lines.

Hatcher's Algebraic Topology

AT_index.info contains index for Hatcher's Algebraic Topology book. Use the following command to add this index to the pdf file:

gs -sDEVICE=pdfwrite -q -dBATCH -dNOPAUSE \
  -sOutputFile=AT_indexed.pdf AT_index.info -f AT.pdf

Fulton's Algebraic Curves

PDF can be cropped using this command:

pdfcrop -bbox-even "140 105 540 700" -bbox-odd "80 105 480 700" CurveBook.pdf

We also have a CurveBook_index.info file to add index to this pdf

gs -sDEVICE=pdfwrite -q -dBATCH -dNOPAUSE \
  -sOutputFile=CurveBook_indexed.pdf CurveBook_index.info \
  -f CurveBook.pdf

Tools

podofo

podofobox can be used to modify the bounding box of a PDF file. It works nicely to crop out the margins of some files, so you can have larger text on an e-reader or tablet device. Something like this would work:

podofobox original.pdf crop.pdf media 5000 5300 34000 58000

Unfortunately podofobox does not support different bounding box for even and odd pages separately.

pdfcpu

A similar command line to add media bounding box:

pdfcpu boxes add -- "media:[50 53 390 633]" original.pdf crop.pdf
