The AdS/CFT correspondence is a conjecture which relates gauge theories to string theories. In order to better understand this duality, several avenues can be taken, …
This dissertation explores several approaches to quantum gravity, all of them adding some quantum features to an otherwise classical theory. The first part is about …
The AdS/CFT correspondence offers a unique possibility for the nonperturbative investigation of gauge theories, through their conjectured equivalence to string theories. In the past years, …
