Terrà un seminario dal titolo:

*“Sacks-Uhlenbeck Scheme in The Context of Dirac-harmonic Maps**”*

*Abstract:*

$\alpha$-Dirac-harmonic maps are variations of Dirac-harmonic maps, analogous to $\alpha$-harmonic maps that were introduced by Sacks-Uhlenbeck to attack the existence problem for harmonic maps from closed surfaces. For $\alpha >1$, the latter are known to satisfy aPalais-Smale condition, and so, the technique of Sacks-Uhlenbeck consists in constructing $\alpha$-harmonic maps for $\alpha >1$ and then letting $\alpha\to1$. In this talk, we will extend this scheme to Dirac-harmonic maps.

Tutti gli interessati sono invitati a partecipare.
