Hello everyone,

Our speaker today is Debanjana Kundu from UBC and at 11am she'll be speaking on "Studying Hilbert's 10th problem via explicit elliptic curves" (abstract below). The seminar today is on Zoom https://washington.zoom.us/j/92671346962.  Please make sure to enter your full name so I know who to let in from the waiting room.

See you later!

Abstract: In 1900, Hilbert posed the following problem: "Given a Diophantine equation with integer coefficients: to devise a process according to which it can be determined in a finite number of operations whether the equation is solvable in (rational) integers."

Building on the work of several mathematicians, in 1970, Matiyasevich proved that this problem has a negative answer, i.e., such a general `process' (algorithm) does not exist.

In the late 1970's, Denef--Lipshitz formulated an analogue of Hilbert's 10th problem for rings of integers of number fields. 

In recent years, techniques from arithmetic geometry have been used extensively to attack this problem. One such instance is the work of García-Fritz and Pasten (from 2019) which showed that the analogue of Hilbert's 10th problem is unsolvable in the ring of integers of number fields of the form $\mathbb{Q}(\sqrt[3]{p},\sqrt{-q})$ for positive proportions of primes $p$ and $q$. In joint work with Lei and Sprung, we improve their proportions and extend their results in several directions.
