"Zero localization: from simple algebra to tantalizing open problems": This talk will be devoted to (precise) zero localization of polynomials, entire and meromorphic functions. This subject goes back at least to Rene Descartes and was developed further by Hermite, Laguerre, Jacobi, Hurwitz, Polya, Szego, Schoenberg, Krein and other giants of our field. I will discuss its historic developments and its connections with other fields, most notably linear algebra.

"Around the Routh-Hurwitz problem": In my second talk, I will focus on the many aspects of the Routh-Hurwitz problem about polynomial stability: algebraic, analytic and matrix-theoretic.
