Arithmetic, Algebra, and Algorithms

 10 - 14 Apr 2023

ICMS, The Bayes Centre, Edinburgh

Scientific Organisers:

  • Alex Bartel, University of Glasgow
  • John Voight, Dartmouth College

About:

Celebrating the Mathematics of Hendrik Lenstra

This workshop brought together leading, as well as early career, researchers on arithmetic statistics and on algorithmic aspects of algebra and number theory, with the aim of fostering collaborations within and between these communities, and offered early career researchers the opportunity to get a broad overview of the most recent achievements and of the most pressing problems in these fields. The workshop also celebrated the mathematics of Hendrik W Lenstra Jr.
