We uncover hidden spectral symmetries of the Teukolsky equation in Kerr(-de Sitter) black holes, recently conjectured by Aminov, Grassi and Hatsuda (arXiv: 2006.06111 arXiv: 2007.07906, 2020) zero cosmological constant case. Using these symmetries, we provide a new, simpler proof mode stability for subextremal Kerr holes. also present partial result Kerr-de Sitter

Abstract Quantum machine learning is a rapidly evolving field of research that could facilitate important applications for quantum computing and also significantly impact data-driven sciences. In our work, based on various arguments from complexity theory physics, we demonstrate single Kerr mode can provide some ‘quantum enhancements’ when dealing with kernel-based methods. Using kernel propert...
