Abstract:

We consider a freely orbifolded AdS₅× S₅ and demonstrate that standard boundary conditions allow states of arbitrarily negative energy. These states describe bubbles that are regular up to singularities due to smeared D3-branes. We discuss the evolution of this data and point out that if the usual boundary conditions are enforced such bubbles may never reach infinity.

Nous étudions l'orbifold AdS₅× S₅ et démontrons que les conditions limites standard permettent des états d'énergie négative de grandeur arbitraire. Ces états décrivent des bulles dont le caractère non singulier n'est limité que par les singularités dues aux branes délocalisées (smeared). Nous analysons l'évolution de ces données et soulignons que si les conditions limites usuelles s'appliquent, alors de telles bulles peuvent ne jamais atteindre l'infini.
