Convergence of nonlocal geometric flows to anisotropic mean curvature motion [PDF]
Discrete and Continuous Dynamical Systems. Series A, 2018 We consider nonlocal curvature functionals associated with positive interaction kernels, and we show that local anisotropic mean curvature functionals can be retrieved in a blow-up limit from them.

Secondary flow and streamwise vortices in three-dimensional staggered wavy-wall turbulence
Flow, 2023 The present paper simplifies the naturally formed dunes (riverbeds) as large-scale three-dimensional staggered wavy walls to investigate the features of the accompanying secondary flows and streamwise vortices via large-eddy simulation.

Propagation of gravity waves and its effects on pseudomomentum flux in a sudden stratospheric warming event [PDF]
Atmospheric Chemistry and Physics, 2020 Effects of realistic propagation of gravity waves (GWs) on distribution of GW pseudomomentum fluxes are explored using a global ray-tracing model for the 2009 sudden stratospheric warming (SSW) event. Four-dimensional (4D; x–z and t) and two-dimensional (

Minimal cones and self-expanding solutions for mean curvature flows [PDF]
Mathematische Annalen, 2019 In this paper, we study self-expanding solutions for mean curvature flows and their relationship to minimal cones in Euclidean space. Ilmanen (Lectures on mean curvature flow and related equations (Trieste Notes), 1995) proved the existence of self ...

Quasiconformal flows on non-conformally flat spheres [PDF]
Advances in Mathematics, 2021 We study integral curvature conditions for a Riemannian metric g on S that quantify the best bilipschitz constant between (S, g) and the standard metric on S.

Generalized Lagrangian mean curvature flows: The cotangent bundle case [PDF]
Journal für die Reine und Angewandte Mathematik, 2016 In [18], we defined a generalized mean curvature vector field on any almost Lagrangian submanifold with respect to a torsion connection on an almost Kähler manifold. The short time existence of the corresponding parabolic flow was established.

A Rigorous Sharp Interface Limit of a Diffuse Interface Model Related to Tumor Growth [PDF]
Journal of nonlinear science, 2016 In this paper, we study the rigorous sharp interface limit of a diffuse interface model related to the dynamics of tumor growth, when a parameter $$\varepsilon $$ε, representing the interface thickness between the tumorous and non-tumorous cells, tends ...

Forced hyperbolic mean curvature flow [PDF]
, 2012 In this paper, we investigate two hyperbolic flows obtained by adding forcing terms in direction of the position vector to the hyperbolic mean curvature flows in \cite{klw,hdl}.

On Type I singularities in Ricci flow [PDF]
, 2011 07.02.13 KB. Accepted version ok to add to Spiral. IP/Sherpa.We define several notions of singular set for Type I Ricci flows and show that they all coincide.
