Endofyear
party 
We encourage you to speak on any date that Dr. Clahane
or Dr. Cowieson
are scheduled to speak (they will gladly postpone their talks to make room for
yours!). Students are encouraged to write their own presentations
of the topics that are covered at any and all meetings and write up the
presentation in LaTeX (see ctan.tug.org for more info
and winedt.com, for example).
The
goal of each meeting is to at the very least, provide each attendee with the
precise statement of an unsolved mathematics problem in any area, even if it is
not in your own specialty  branching out is encouraged!

There is risk, but there is also reward.
Thanks to a $1900 grant from the Office of Staff Development, the
Colloquium’s Fall 2010 unfunded status is no longer! In Spring and
Summer, as a result, we will be able to provide honoraria for external
speakers.

would like to thank Lucia Ly (entering UCLA in Fall ’11) and Rheza Hidajat (entering UC
Berkeley in Fall ‘11) for their gracious volunteer homework grading assistance,
which has freed him up a bit to work on these webpages
and perform other related tasks this semester. Dr. Clahane would
also like to thank Wilson Lee (entering UCLA as a freshman in Fall ’11), who
graciously provided other grading assistance at the end of the semester. MATHEMATICS
