Dear Xu Guangwu:

Your knowledge in the areas you want to study probably exceeds my own,
but other professors here are well qualified in computational complexity and
computational applications of algebra.  I have requested that information
on application to our doctoral program be sent to you.  You might also
consider Stanford's mathematics department, where Professor Feferman and
others direct research in recursive function theory.

\closing
Sincerely yours,
Robert W. Floyd
