This study introduces a generalized minimizing movement scheme for mean curvature flow, replacing volume penalization with a novel integral term. The scheme converges to a geometric evolution equation, preserving convexity under certain conditions.
Area of Science:
- Geometric Analysis
- Partial Differential Equations
- Calculus of Variations
Background:
- The Almgren-Taylor-Wang scheme is a method for mean curvature flow.
- De Giorgi's conjecture motivates exploring generalized penalization terms.
- Understanding the convergence of discrete schemes to continuous evolution equations is crucial.
Purpose of the Study:
- To analyze a generalized minimizing movement scheme for mean curvature flow.
- To investigate the convergence of this scheme to a specific geometric evolution equation.
- To extend the analysis to anisotropic settings and driving forces.
Main Methods:
- Utilizing a generalized minimizing movement scheme with a novel integral penalization term.
- Analyzing the convergence properties of the scheme.
- Extending the framework to anisotropic mean curvature flow and flows with driving forces.
Main Results:
- The generalized minimizing movement scheme converges to the geometric evolution equation f(v) = -κ on ∂E(t).
- The analysis is extended to anisotropic settings and flows with driving forces.
- Minimizing movements are shown to coincide with smooth classical solutions when they exist.
- Mean convexity and convexity are preserved by the weak flow in the absence of forcing.
Conclusions:
- The proposed generalized minimizing movement scheme provides a robust framework for studying mean curvature flow.
- The convergence to the geometric evolution equation is established for a broad class of functions f.
- The study offers insights into the behavior of geometric evolution equations in various settings.
