    Project Guidelines
    No two students may choose the same paper.
    Read the selected paper, and fill in ALL mathematical details as completely as possible
    Provide a summary of the paper in words, describing methods used and main results
    Rules: Each project is to be independent student work
    You must understand everything you have written down.
    If there are some numerical results in the paper, discuss how they relate to the analysis.
    Score on the final project will be based on completeness and clarity of presentation
    The difficulty level of the paper will also be taken into account.
