Each
participant in our program produces a paper describing their results. As
the program is only eight weeks long, participants don't have much time to
revise and polish their papers. When viewing the papers below, please
keep in mind that they are not intended to be final versions, but are works in
progress. The students have worked hard to produce these results, and
have done a great job! The research represented by these papers was made
possible by NSF-REU grants DMS-9987955, DMS-0139426, DMS-0453605, and
DMS-0850959 as well as the generous support of California State University, San
Bernardino.
