Commutative algebra 3 (What is a syzygy?)
This lecture is part of an online course on commutative algebra, following the book "Commutative algebra with a view toward algebraic geometry" by David Eisenbud. We give several examples of rings of invariants and syzygies. Correction: Near the end (last but one sheet) I missed out one

Symmetries show up everywhere in physics. But what is a symmetry? While the symmetries of shapes can be interesting, a lot of times, we are more interested in symmetries of space or symmetries of spacetime. To describe these, we need to build "invariants" which give a mathematical represen

Syzygies, gonality and symmetric products of curves - Robert Lazarsfeld
Robert Lazarsfeld Stony Brook University April 14, 2015 In the mid 1980s, Mark Green and I conjectured that one could read off the gonality of an algebraic curve CC from the syzygies among the equations defining any one sufficiently positive embedding of CC. Ein and I recently noticed that

This lecture is part of an online course on rings and modules. We prove Hilbert's theorem that poynomial rings over fields are Noetherian, and use this to prove Hilbert's theorem about finite generation of algebras of invariants, at least for finite groups over the complex numbers. For

Juliette Bruce - Semi-Ample Asymptotic Syzygies - WAGON
I will discuss the asymptotic non-vanishing of syzygies for products of projective spaces, generalizing the monomial methods of Ein-Erman-Lazarsfeld. This provides the first example of how the asymptotic syzygies of a smooth projective variety whose embedding line bundle grows in a semi-am
