The following folders will contain the problem sets for the course, in LaTeX, DVI, PostScript and PDF formats. There exists free software for viewing all of these: PDF can be read with Adobe Acrobat , PostScript with Ghostview and DVI with DVI Scope. (Note: DVI Scope is only for Windows systems. I'm not sure what to do on a Mac. Red Hat ships with xdvi, I'm not sure where to download it from if you have a non-Red Hat Linux, but you can always copy it from a Red Hat neighbor.) LaTeX and TeX are not meant to be read directly but rather to be converted to DVI, software for this purpose can be found here. LaTeX is also nice in that, in a pinch, you can just open it in a word processor and figure out what it means with a little experience. This site has guides to the most frequent TeX symbols, not enough to write it but it should give you a reading knowledge.

A few notes on viewing these formats from a UNIX terminal. The programs tex and latex respectively will convert a TeX or LaTeX file to a DVI file. Call them with the syntax tex filename.tex or latex filename.tex After TeX is done, it will display a single *, type \end.xdvi will display DVI files, call it with the syntax xdvi filename.dvi dvips will convert files from DVI to PS, call it with the syntax dvips -o filename.ps filename.dvi gs will view a PS file, call it as gs filename.ps ps2pdf will convert from PS to PDF, call it as ps2pdf filename.ps filenname.pdf pdf2ps does the reverse, call it as pdf2ps filename.pdf filename.ps Adobe will view PDF files, but I'm not sure off the top of my head of how to call it from a command line. If you open a PDF file using Netscape, it will automatically launch Adobe. Of course, you have to be at an X terminal to use any of the viewers, but the file converters will work anywhere.

Wow, my "short guide" to viewing files is longer than the math! I'll try to make up for that later.

The midterms are here. Both Professor Kazhdan and I wound up writing solution sets for the midterm, here they are.

Solutions to the second midterm (the same as were handed out in class) are here.

  • LaTeX
  • DVI
  • PS
  • PDF

    The following folders contain the course solution sets, in similar formats. One note though: professor Kazhdan, because he wants his problem sets to look good, has written them in LaTeX; I, because I want to write them fast, have written them in ordinary TeX.

  • TeX
  • DVI
  • PS
  • PDF

    At times, professor Kazhdan will send me proofs to post of results that he plans to later present in class. These will be placed in the folders below.

  • LaTeX
  • DVI
  • PS
  • PDF
