About COIN
  COIN, or COalgebra in the Netherlands, is a seminar taking place
  alternating at the Radboud University in Nijmegen and the CWI in
  Amsterdam. The aim of COIN is to bring together coalgebra researchers
  from various locations in the Netherlands, and share current results
  and questions in the world of coalgebra. We welcome presentations on
  any subject related to coalgebra.
  If you would like to present your work at COIN, please let us know.
  We would be happy to have you as a speaker.
