%% Notes:
%%   1) A proof environment is defined in this file.  It must be removed
%%      if an included package (e.g., amsmath) also defines this environment
%%      or an error will result.
%%   2) Theorem-like environments are defined (using the environment name
%%      in parenthesis) for Theorem (theorem), Lemma (lemma),
%%      Corollary (corollary), Problem (problem), Definition (definition),
%%      Assumption (assumption), Example (example), and Remark (remark).
%%   3) Remember that the abstract must be submitted separately from the
%%      thesis, and that six copies must be submitted.
%%   4) Remember to include two blank pages before the title page and after
%%      the vita.
