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