| Abstract | The study of zero distribution of random polynomials has a long history and is currently a very
active research area. Traditionally, the randomness in these polynomials comes from the probability
distribution followed by their coefficients. One can introduce randomness in the zeros (instead of
the coefficients) of polynomials, and then investigate the locations of their critical points (relative to
these zeros). Such a study was initiated by Rivin and the late Schramm in 2001, but only until 2011,
Pemantle and Rivin proposed a precise probabilistic framework of it which will first be explained in
this talk. Following this framework, we will consider the problem of finding the zero distributions of the
derivatives of random polynomials and random finite Blaschke products with i.i.d. zeros following a
common distribution supported on a subset of the complex plane. This is a joint work with Pak-Leong
Cheung, Jonathan Tsai and Phillip Yam. |
