Witness and Pseudowitness Sets in Numerical Algebraic Geometry

This lecture by Jonathan Hauenstein from the University of Notre Dame explores witness and pseudowitness sets in numerical algebraic geometry. Scheduled for Tuesday, May 27, 2025, as part of the Fields Institute's program on commutative algebra applications, the 38-minute presentation delves into fundamental concepts that bridge numerical methods and algebraic geometry. Learn about these powerful computational tools that enable the numerical representation and manipulation of algebraic sets, which are essential for solving systems of polynomial equations and understanding their solution structures.
