Flow by powers of the gauss curvature
WebMar 9, 2024 · Over the last decades, the subject of extrinsic curvature flows in Riemannian manifolds has experienced a significant development. Along this time, special attention has been given to mean curvature and Gaussian curvature flows in Euclidean space, resulting in achievements such as the proof of short time existence of solutions and their … Webv. t. e. Asymptotic safety (sometimes also referred to as nonperturbative renormalizability) is a concept in quantum field theory which aims at finding a consistent and predictive quantum theory of the gravitational field. Its key ingredient is a nontrivial fixed point of the theory's renormalization group flow which controls the behavior of ...
