Title: Rational Diophantine tuples and elliptic curves
Date/Time: December 2, 2019 / 12.40-13.30
Place: FENS G032
Abstract: Elliptic curves have received considerable attention from both mathematicians and computer scientists over the past 40 years. One of the main open questions in mathematics, the Birch and Swinnerton-Dyer conjecture, was formulated in the 60's as a result of extensive computer experiments in Cambridge University. I will go over the formulation of the conjecture and state some recent result on the formula for the leading term. We will then discuss questions from elliptic curve cryptography related to computation of isogenies and their applications to public-key cryptography. In the second part of the talk, I will discuss novel methods for high-precision privacy-preserving computing based on techniques from secure multiparty computation and Fourier approximations. We will finish by discussing some experimental results.
