A special day of activities related to computation in combinatorial algebraic geometry.

### Installing Macaulay2

Friday, 21 October 2016 from 09:00 to 10:00 in Room 309, Fields Institute

Drop by, at any point during the hour, to get assistance installing and setting up the Macaulay2 software system on your laptop.

### Macaulay2 basics

Friday, 21 October 2016 from 09:00 to 10:00 in Room 309, Fields Institute

During this interactive tutorial, the participants will solve some mathematical problems using Macaulay2. Since small groups will work on different problems, not everyone needs to bring a laptop. People who have not used Macaulay2 before are especially welcome. Some suggested problems and solutions are available.

### Using Macaulay2 in research

Friday, 21 October 2016 from 11:00 to 12:00 in Room 309, Fields Institute

In this talk, Mike Stillman (Cornell) will describe some interesting mathematical problems and show how to investigate them using Macaulay2. For example, given a Calabi-Yau hypersurface in a toric 4-fold, can one use intersection theory to find rigid divisors (these will be defined!)? This question is central to an ongoing collaboration with some string theorists.

### Ask Mike?

Friday, 21 October 2016 from 15:30 to 16:30 in Room 309, Fields Institute

Mike Stillman will do his best answer any and all questions. Some natural candidates include: How do I do *X* in Macaulay2? Why does Macaulay2 do *Y*? How can I compute *Z* more efficiently?

The code Mike created during the session can be found here

### Coding support group

Friday, 21 October 2016 from 16:30 to 17:30 in Room 309, Fields Institute

Unstructured time to work on code with many experts around to provide assistance (if needed).
