Extinction and persistence of populations in a random environment: generalization to density-dependent noise intensities

Abstract

Scientific paper on stochastic differential equation models of population growth in a random environment extending previous results on extinction and persistence to the case of density-dependence noise intensities. The paper is contained in the book of Proceedings of the international conference Probability and Statistics in Science and Engineering 2007 (Porto, 2007, organised by the Bernoulli Society).
