Abstract
A general framework for the study of the formation of apparent horizons is found. A necessary condition is given in momentarily static nonspherical geometries with non-negative (locally) sectional curvatures. Known results concerning the existence of trapped surfaces are reviewed in a class of conformally flat nonspherical systems.Keywords
