That sugra is very important to string theory and m theory. But, it seems to be non renormalizable. But could it asymptotic safe, non perturbatively, like Reuter argues for EH action?
Do you know something about the current status?MTd2 said:... it seems to be non renormalizable.

SUGRA N=1 in 11D asymptotic safe a la Reuter refers to a specific supersymmetric theory called Supergravity (SUGRA) in 11 dimensions, which has been proposed to be asymptotically safe based on the research of physicist Martin Reuter. Asymptotic safety is a theory in quantum gravity that suggests the existence of a fixed point in the renormalization group flow, allowing for a consistent and well-defined theory of gravity.
The "N=1" in SUGRA N=1 refers to the amount of supersymmetry present in the theory. In this case, it means that there is one supersymmetry generator, making it a minimal supersymmetric theory.
SUGRA N=1 in 11D is a low energy limit of string theory, specifically Type IIA string theory. This means that at low energies, the behavior of SUGRA N=1 in 11D matches that of Type IIA string theory, providing a connection between the two theories.
The idea of asymptotic safety in quantum gravity is significant because it suggests the possibility of a renormalizable theory of gravity, which has been a long-standing challenge in theoretical physics. This could potentially resolve the conflicts between general relativity and quantum mechanics and provide a more complete understanding of the universe.
There is still ongoing research and debate about the validity of SUGRA N=1 in 11D being asymptotically safe. Some studies have shown promising results, but it is still a relatively new and untested theory. More research and experimentation is needed to definitively determine its validity.
