THEORIA 64 (2009): 229-247 Evolution Nodes in Newtonian Supertasks

ABSTRACT: The present article provides an analysis of the instants of a system that performs a Newtonian supertask. For each instant it studied the possibility of the system having, from the instant in question, more than one possible course of evolution; i.e. the possibility of it being an evolution node. This analysis shows that some supertasks presented as deterministic in Pérez Laraudogoitia (2007) are in fact indeterministic and specifies the difficulties ahead in showing the radical indeterminism suggested by Atkinson & Johnson (2009)
