Action Minimizers This book concentrates mainly on the theorem of existence of periodic orbits for higher dimensional analogs of Twist maps. The setting is that of a discrete variational calculus and the techniques involve Conley-Zehnder-Morse Theory. They give rise to the concept of ghost tori which are of interest in the dimension 2 case (ghost circles). The debate is oriented somewhat toward the open problem of finding orbits of all (in particular, irrational) rotation vectors. <br><i>Contents: </i><ul><li>Twist Maps of the Annulus</li><li>The Aubry-Mather Theorem</li><li>Ghost Circles</li><li>Symplectic TwAdvanced series in nonlinear dynamics ;v. 18.Twist mappings (Mathematics)Mappings (Mathematics)Electronic books.Twist mappings (Mathematics)Mappings (Mathematics)514.74Golé Christophe967840MiAaPQMiAaPQMiAaPQBOOK9910453547503321Symplectic twist maps2197997UNINA
