Triangle Lectures in Combinatorics (TLC)

Twelfth meeting: Saturday October 3, 2015, 9:15am -- 6pm.

Location: Duke University (Physics building, room 128).

Speakers: Yuliy Baryshnikov (UIUC), Susan Holmes (Stanford), Dana Randall (Georgia Tech), and John Shareshian (Washington University in St. Louis).

Preregistration: please send email to (Patricia Hersh) to preregister. This is very helpful in our planning how much coffee, etc. to have at coffee breaks and for our obtaining funding to support these meetings.

Participant Travel Expense Reimbursement: we have some funding available for some participants, especially for early-career participants. Most of this is restricted to U.S. citizens, and what is available to others still requires that the participants be employed at a U.S. university. To request funding please fill out the form here.

Poster Session: This meeting of a Triangle Lectures in Combinatorics will have a poster session. To request a slot in the poster session please fill out the following webform. There will be 10 poster slots in total and all reasonable posters will be accepted on a first-come first-served basis.

Friday Colloquium: in addition to the conference talks at Duke on Satuday, Oct. 3rd, there will also be a math colloquium talk by Persi Diaconis at 4pm on Friday, Oct. 2nd at North Carolina State University (in Raleigh NC, which is about 30 minutes drive from Duke).

Directions: The Mathematics Department is located in the Physics Building, which is at the end of Science Drive, almost opposite the the Bryan Center, on the West Campus of Duke University. If you approach from the front of the building, the department is on the left hand side. The main departmental offices are in room 117 on the first floor, the same level as the main entrance of the building. Parking is immediately to the right of the building from the following perspective picture of the physics building (map).

In the above map locate the point Towerview Rd and Science Dr. To locate the parking lot on the map drive along Sciences Dr. towards the traffic circle. At the traffic circle go 3/4 around the circle and parking will be on your right. This is immediately next to the Physics Building. This streetview shows you are entering the traffic circle and to your left you can see the gate the the parking lot for the Math department.

Parking: We have purchased 45 parking passes for the lot immediately next door to the physics building, just to the right of it on Science Drive. But you will need to get one of these passes and to swipe it to enter the lot. Our plan is to leave parking passes in a water-proof box next to the gate. Please only take one pass!

A good back-up option is parking at the Sarah Duke Gardens for a fee. Parking at Sarah Duke Gardens will require a walk across campus to the physics building, so participants are advised (1) to allow time for this walk, (2) to print a campus map in advance since the route to the physics building may be confusing, and (3) to bring an umbrella since it may be very rainy. Participants who arrive late for the conference will likely need to park at the Sarah Duke Gardens.
