On the stability of backgrounds with -deformed factors
Georgios Itsios, Pantelis Panopoulos, Konstantinos Sfetsos +1
We investigate the stability of the non-supersymmetric solutions of type-IIB supergravity having an unwarped factor and -deformed subspaces found in arXiv:1911.12371. Amon…

Exact results from the geometry of couplings and the effective action
George Georgiou, Pantelis Panopoulos, Eftychia Sagkrioti +1
We invent a method that exploits the geometry in the space of couplings and the known all-loop effective action, in order to calculate the exact in the couplings anomalous dimensio…

The exact -function in integrable -deformed theories
George Georgiou, Pantelis Panopoulos, Eftychia Sagkrioti +2
By employing CFT techniques, we show how to compute in the context of λ-deformations of current algebras and coset CFTs the exact in the deformation parameters C-function for a wid…
