International Workshop Hausdorff Geometry of Polynomials

July 10, 2023 - July 14, 2023

The workshop Hausdorff Geometry of Polynomials is devoted to the study of properties of polynomial functions such as their zeros and their growth, along with asymptotic properties of sequences of polynomials and their applications in many areas of mathematics, mathematical physics, and probability theory. The works presented honor the memory of Academician Blagovest Sendov who has made substantial contributions to the subject.

The workshop is within the frame of the International Conference “Mathematics Days in Sofia”
