DESCRIPTION:Speakers: Michele Serra (TU Dortmund)\n\nIn 1882\, Kronecker e
 stablished that a given univariate formal Laurent series over a field can 
 be expressed as a fraction of two univariate polynomials if and only if th
 e coefficients of the series satisfy a linear recurrence relation. In this
  talk I report on joint work with L.S. Krapp and S. Kuhlmann where we intr
 oduce the notion of generalised linear recurrence relations for power seri
 es with exponents in an arbitrary ordered abelian group generalising Krone
 cker’s original result. Moreover\, we study distinguished subfields of a
  power series field\, which are determined by generalised linear recurrenc
 e relations.\n\nhttps://math-events.uni-bonn.de/event/498/
