Bernd Sturmfels (University of California at Berkeley)


We present a computational study of plane curves of degree four, with primary focus on representing their defining polynomials as sums of squares and as symmetric determinants. Based on joint work with Daniel Plaumann and Cynthia Vinzant, this lecture spans the bridge from 19th century algebraic geometry to 21st century polynomial optimization theory.

About the speaker

Bernd Sturmfels received doctoral degrees in Mathematics in 1987 from the University of Washington and the Technical University Darmstadt, Germany. He joined UC Berkeley in 1995, where he is Professor of Mathematics, Statistics and Computer Science. His honors include a National Young Investigator Fellowship, a Sloan Fellowship, and a David and Lucile Packard Fellowship, a Clay Senior Scholarship, an Alexander von Humboldt Senior Research Prize, and the SIAM von Neumann Lecturership. Recently, he served as Vice President of the American Mathematical Society. Sturmfels has authored ten books and 200 research articles, in the areas of combinatorics, algebraic geometry, symbolic computation and their applications. His current research focuses on algebraic methods in optimization, statistics, and computational biology.
