Almost twenty years after conception of the first edition, itwas a challenge to prepare an updated version of this text on theCalculus of Variations. The field has truely advanced dramaticallysince that time, to an extent that I find it impossible to give acomprehensive account of all the many important developments thathave occurred since the last edition appeared. Fortunately, anexcellent overview of the most significant results, with a focus onfunctional analytic and Morse theoretical aspects of the Calculusof Variations, can be found in the recent survey paper byEkeland-Ghoussoub [1]. I therefore haveonly added new materialdirectly related to the themes originally covered.
Even with this restriction, a selection had to be made. In viewof the fact that flow methods are emerging as the natural tool forstudying variational problems in the field of Geometric Analysis,an emphasis was placed on advances in this domain. In particular,the present edition includes the proof for the convergence of theYamabe flow on an arbitrary closed manifold of dimension 3 m 5 forinitial data allowing at most single-point blow-up.Moreover, wegive a detailed treatment of the phenomenon of blow-up and discussthe newly discovered results for backward bubbling in the heat flowfor harmonic maps of surfaces.
Aside from these more significant additions, a number of smallerchanges have been made throughout the text, thereby taking care notto spoil the freshness of the original presentation. Referenceshave been updated, whenever possible, and several mistakes that hadsurvived the past revisions have now been eliminated. I would liketo thank Silvia Cingolani, Irene Fouseca, Emmanuel Hebey, andMaximilian Schultz for helpful comments in this regard. Moreover,Iam indebted to Gilles Angelsberg, Ruben Jakob, Reto Miiller, andMelanie Rupfiin, for carefully proof-reading the newmaterial.
