*"**Hylomorphic solitons**"*

**

**

/Abstract: Roughly speaking a solitary wave is a solution of a .eld 
equation whose/

/energy travels as a localized packet and which preserves this 
localization in time./

/A soliton is a solitary wave which exhibits some strong form of 
stability so that it/

/has a particle-like behavior. This talk is devoted to solitary waves 
and solitons/

/whose existence is related to the ratio (energy)/(hylenic charge). The 
name hylenic/

/charge refers to an other invariant of motions which depends on the 
particular/

/equation we are dealing with. The class of hylomorphic solitons 
includes the Qballs,/

/which are spherically symmetric solutions of the nonlinear Klein-Gordon/

/equation, as well as solitary waves which occur, by the same mechanism, 
in the/

/nonlinear Schroedinger equation and in gauge theories. Also waves in 
nonlinearly/

/supported beams can be considered hylomorphic solitons./

*15:45 Uhr -- 16:15 Uhr K & K (Sky Lounge)*
