Speaker: Phạm Việt Hùng

Venue: Room 612, A6, Institute of Mathematics, VAST

Abstract: In this talk, we review some results on the expected number of zeros of random polynomials in two cases: real and p-adic. For the real case, we present the Kac-Rice formula and its geometric meaning through Integral Geometry . To extend these ideas to the p-adic case, we discuss the works of Evans; Kulkarni and Lerario.
