You are cordially invited to attend and give a short talk at our Knots in Washington XVIII conference.
This regional conference is held every semester, in various locations in the Washington area
(see zytyck/knots/index.html ).

The conference will take place at George Washington University.

We plan six plenary talks - 60 minutes long, and 20-30 minutes long research talks.

You are cordially invited to participate in this and future meetings. We will start on May 28, 10:30am (Rome Hall 801 22nd St. NW).
If you plan to attend please contact one of the organizers. No registration fee! 

We have limited partial NSF support for PhD students, fresh PhD's and mathematicians without a grant.

Comments from Mike Veve:
The conference is scheduled during the Memorial Day weekend. This means two things
1) Traffic will be very heavy on Friday.
2) It will be impossible to drive into GW on Sunday. Sunday is the day of the big motorcycle festival called Rolling Thunder. It takes place on the Mall and cars will not be able to get in and out of Foggy Bottom unless you go through Georgetown. Everyone will be forced to do this so traffic will be at a standstill.
For Sunday, metro is the best option for getting to GW.
