DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/HAC/8
 /">Indecomposable algebraic integers</a>\nby Hendrik Lenstra (Universiteit
  Leiden) as part of Heilbronn Annual Conference 2020\n\n\nAbstract\nThe ri
 ng of all algebraic integers carries the structure of a "Hilbert lattice"\
 , which means that its additive group may be viewed as a discrete subgroup
  of a Hilbert space. As a consequence\, that group is generated by the set
  of "indecomposable algebraic integers". There are not too many of those\;
  in fact\, only finitely many for each degree. The lecture surveys what we
  know and what we would like to know about these indecomposable algebraic 
 integers. It represents joint work with Ted Chinburg and Daan van Gent.\n
