DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCDANT/16/">
 Isometries of lattices\, knot theory and K3 surfaces</a>\nby Eva Bayer-Flu
 ckiger (EPFL) as part of Dublin Algebra and Number Theory Seminar\n\n\nAbs
 tract\nWe give necessary and sufficient conditions for an integral polynom
 ial to be the characteristic polynomial of an isometry of some even\, unim
 odular lattice of given signature. This result has applications in knot th
 eory (existence of knots with given Alexander polynomial and Milnor signat
 ures) as well as to K3 surfaces (existence of K3 surfaces having an automo
 rphism with given dynamical degree).\n
