[图书][B] Ricci flow and the sphere theorem

S Brendle - 2010 - books.google.com
" In 1982, R. Hamilton introduced a nonlinear evolution equation for Riemannian metrics
with the aim of finding canonical metrics on manifolds. This evolution equation is known as …

Non-collapsing in fully non-linear curvature flows

B Andrews, M Langford, J McCoy - Annales de l'Institut Henri Poincaré C …, 2013 - Elsevier
We consider compact, embedded hypersurfaces of Euclidean spaces evolving by fully non-
linear flows in which the normal speed of motion is a homogeneous degree one, concave or …

Ricci flow on surfaces along the standard lightcone in the -Minkowski spacetime

M Wolff - Calculus of Variations and Partial Differential …, 2023 - Springer
Identifying any conformally round metric on the 2-sphere with a unique cross section of the
standard lightcone in the 3+ 1-Minkowski spacetime, we gain a new perspective on 2 d-Ricci …

A De Lellis–Müller type estimate on the Minkowski lightcone

M Wolff - Calculus of Variations and Partial Differential …, 2024 - Springer
We prove an analogue statement to an estimate by De Lellis–Müller in R 3 on the standard
Minkowski lightcone. More precisely, we show that under some additional assumptions, any …

Isoperimetric comparisons via viscosity

L Ni, K Wang - The Journal of Geometric Analysis, 2016 - Springer
Viscosity solutions are suitable notions in the study of nonlinear PDEs justified by estimates
established via the maximum principle or the comparison principle. Here we prove that the …

produced using the maximum principle applied to functions depending on several points …

An area growth argument for null mean curvature flow along the standard de Sitter lightcone

M Wolff - arXiv preprint arXiv:2312.07317, 2023 - arxiv.org
We consider null mean curvature flow along the standard lightcone in the de Sitter
spacetime. This flow was first studied by Roesch--Scheuer along null hypersurfaces for the …

Uniform Lipschitz continuity of the isoperimetric profile of compact surfaces under normalized Ricci flow

Y Zheng - Proceedings of the American Mathematical Society, 2021 - ams.org
We show that the isoperimetric profile $ h_ {g (t)}(\xi) $ of a compact Riemannian manifold
$(M, g) $ is jointly continuous when metrics $ g (t) $ vary continuously. We also show that …
