We ask our colloquium speakers to please make every effort to make the talks understandable to second year graduate students and to faculty from all areas of mathematics. It is usually best if a talk contains at least one concrete mathematical idea: a small piece of a proof that can be isolated, a particularly important and nonobvious definition, etc.

We now also have a tradition of having an informal pre-colloquium lunch, meant for the speaker to give an informal and brief introduction to the topic of the main lecture for the benefit of our graduate students and others. However, attending this lunchtime talk should not be a prerequisite for understanding the colloquium lecture itself.

Our colloquium room has 6 blackboards, two overhead projectors, and hookup for digital projection (in landscape format) from a laptop. You are welcome to use whichever technology suits you best. During the lunchtime talk we prefer a blackboard presentation.

The organizers would be grateful if you could send a mathematical image related to the subject of the talk and a photograph of yourself to be put on our colloquium poster.

We are looking forward to your talk at the Princeton math colloquium!
