Title: Painleve's determinateness theorem extended to proper coverings Author: Claudi Meneghin (Isrc, Chiasso, Switzerland) Abstract: We extend Painleve's determinateness theorem to first-order ordinary differential equations in the complex domain, with known terms allowed be multivalued in the dependent variable. The multivaluedness is supposed to be resolved by proper coverings. Submitted January 23, 2009. Published April 19, 2010. Math Subject Classifications: 34M35, 34M45.
