talks and papers listed below often contain mathematical formulas.
If you have trouble viewing the symbols and Greek letters in these formulas,

However, once it finishes, it is completely self-contained.
Portable Document Format (PDF) for viewing using
Adobe Acrobat Reader.
This format is suitable for viewing and printing the fully formatted
