### Cayley-Bacharach Relations and Sums of Squares

- Series
- Student Algebraic Geometry Seminar
- Time
- Monday, November 11, 2019 - 13:30 for 1 hour (actually 50 minutes)
- Location
- Skiles 254
- Speaker
- Kevin Shu – Georgia Tech (grad student) – kshu8@gatech.edu

This talk is based on a paper by Grigoriy Blekherman. In most cases, nonnegative polynomials differ from positive polynomials. We will discuss precisely what equations cause these differences, and relate them to the well known Cayley-Bacharach theorem for low degree polynomials.
