An inequality for the minimum affine curvature of a plane curve
As an application of the affine curve shortening flow, we will prove an inequality for minimum affine curvature of a smooth simple closed curve in the Euclidean plane. Résumé. Comme application du

The paper (in French) exemplifies graphically a solution of the heat equation which is a 1-dimensional unfolding of an elliptic umbilic catastrophe. The example is due to James Damon and adapts

On a General Linear Nonlocal Curvature Flow of Convex Plane Curves
Motivated by Pan-Yang [PY] and Ma-Cheng [MC], we study a general linear nonlocal curvature flow for convex closed plane curves and discuss the short time existence and asymptotic convergence behavior
Expanding convex immersed closed plane curves
We study the evolution driven by curvature of a given convex immersed closed plane curve. We show that it will converge to a self-similar solution eventually. This self-similar solution may or may
Application of Andrews and Green-Osher inequalities to nonlocal flow of convex plane curves
We shall apply certain inequalities by Andrews and Green-Osher to area-preserving and length-preserving flows of convex plane curves and show that, if we have bound on the curvature, the evolving
Inextensible Flows of Curves in Minkowskian Space
In this paper we investigate inextensible flow of curves in Minkowski 3-space. Necessary and sufficient conditions for an inextensible curve flow are expressed as a partial differential equation
Curvature estimates for graphical mean curvature flow in higher codimension
I consider deformations of maps f : M→ N under the mean curvature flow, i. e. the mean curvature flow of the graph Γ( f ) of f in M× N. Let M be a compact and N be a complete Riemann surface, such
On a Logarithmic Type Nonlocal Plane Curve Flow
In this paper the author devotes to studying a logarithmic type nonlocal plane curve flow. Along this flow, the convexity of evolving curve is preserved, the perimeter decreases, while the enclosed
On Inextensible Flows of Curves According toType-2 Bishop Frame in E3
In this paper, we study inextensible flows of curves in Euclidean space 3 E . Using the Frenet frame of the given curve, we present partial differential equations. We give some characterizations for

Flow by mean curvature of convex surfaces into spheres
The motion of surfaces by their mean curvature has been studied by Brakke [1] from the viewpoint of geometric measure theory. Other authors investigated the corresponding nonparametric problem [2],
BONNESEN-STYLE ISOPERIMETRIC INEQUALITIES
Because of Property 1, any Bonnesen inequality implies the isoperimetric inequality (1). From Property 2, it follows that equality can hold in (1) only when C is a circle. The effect of Property 3 is
