The Twentieth Bay Area Discrete Math Day (BADMath Day) will take place on the campus of Santa Clara University, Saturday, April 24, 2010 between 10:00 AM and 5:00 PM. All talks will be held in the Williman Room in the Benson Memorial Center. BADMath Days are one-day meetings aimed at facilitating communication between researchers and graduate students of discrete mathematics around the San Francisco Bay Area. These days happen twice a year and strive to create an informal atmosphere to talk about discrete mathematics. The term "discrete mathematics" is chosen to include at least the following topics: Algebraic and Enumerative Combinatorics, Discrete Geometry, Graph Theory, Coding and Design Theory, Combinatorial Aspects of Computational Algebra and Geometry, Combinatorial Optimization, Probabilistic Combinatorics, Combinatorial Aspects of Statistics, and Combinatorics in Mathematical Physics.

There is no registration fee, but please fill out the registration form on or before Wednesday, April 14 (registration is now closed). This is essential so that we know how much food to get for lunch.

Lunch will be provided on-site (if you registered). There will also be a dinner following the conference, subsidized by a donation from the D.E. Shaw Group, and everyone is more than invited to attend. Both will be vegetarian- and vegan-friendly.

The schedule is listed below. For abstracts, scroll over the title or, to see all at once, go to the abstracts page.

We will be helping to organize carpools. If you are driving and have room for passengers or if you would like to be a passenger, then please contact a local organizer near you.

If you prefer to take public transportation, Caltrain stops at the main entrance to the SCU campus (the Santa Clara stop). From this stop, it is about a 10-15 minute walk to the Benson Center. There is a Caltrain leaving San Francisco at 8:15 and arriving at the Santa Clara station at 9:43 AM. From the East Bay, there is no good option. We recommend driving, but if this is completely out of the question, BART to Millbrae to pick up the Caltrain is theoretically possible, as is Amtrak to San Jose and then a bus to Santa Clara.
