DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/20/">Re
 presentations for complex numbers with integer digits</a>\nby Paul Surer (
 University of Natural Resources and Life Sciences\, Vienna) as part of One
  World Numeration seminar\n\n\nAbstract\nIn this talk we present the zeta-
 expansion as a complex version of the well-known beta-expansion. It allows
  us to expand complex numbers with respect to a complex base by using inte
 ger digits. Our concepts fits into the framework of the recently published
  rotational beta-expansions. But we also establish relations with piecewis
 e affine maps of the torus and with shift radix systems.\n
