Macaulay 2 is a specialized computer algebra system for computing in
algebraic geometry and commutative algebra (and related fields). The
system is under active development, is freely available for linux, MacOS,
Windows, and other systems, and is being used by many researchers. Dan
Grayson (of University of Illinois) and I have been working on this project
since 1993.
We show some ways that Macaulay 2 can be used to aid research in algebraic
geometry. One of our examples will be a "mystery curve", and we will
attempt to understand the structure of this curve. Along the way, we will
see how to compute with ideals, Groebner bases, syzygies, divisors, and
projective geometry.
One goal of the talk is to give some idea of what can currently be computed
in algebraic geometry, in general, and also to give an indication
of what Macaulay 2 is capable of.
