The papers collected in this volume are contributions to the 43rd session of the Seminaire de mathematiques superieures (SMS) on Morse Theoretic Methods in Nonlinear Analysis and Symplectic Topology. This session took place at the Universite de Montreal in July 2004 and was a NATO Advanced Study Institute (ASI). The aim of the ASI was to bring together young researchers from various parts of the world and to present to them some of the most signi cant recent advances in these areas. More than 77 mathematicians from 17 countries followed the 12 series of lectures and participated in the lively...
