Jordan Frame in Supergravity and Cosmology
Renata Kallosh
The superconformal action can be gauge-fixed in a gauge where is leads to the Einstein frame supergravity defined by a Kahler potential , or in a gauge where it leads…
New Exponential and Polynomial -attractors
Renata Kallosh, Andrei Linde
We introduce a new family of cosmological attractors with non-minimal coupling of gravity and non-canonical kinetic terms. In the Einstein frame, these models transform into a clas…
Anomaly cancellation and one-loop finiteness of 6D half-maximal supergravities
Renata Kallosh
We suggest that the surprising one-loop finiteness of 6D half-maximal supergravities recently discovered in \cite{Huang:2025nyr} might be related to anomaly-free G-dual…
On anomaly free 4d =4 and 6d (2,0) conformal supergravities and UV finiteness of Poincaré supergravities
Renata Kallosh, Arkady A. Tseytlin
We review the structure of superconformal anomalies in 4d =4 conformal supergravity (CSG) coupled to a number N$_\rm v$ of =4 vector multiplets and 6d (2,0…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
The role of Sp(2n) duality in quantum theory
Renata Kallosh
D-dimensional maximal supergravities type I with G/H coset spaces have global G-symmetry and local H symmetry, which can be gauge-fixed in symmetric or Iwasawa-type gauges. Maximal…
