無中文摘要
For N a natural number and any given initial equilateral N-gon, we obtain the long-time existence of
smooth solution equilateral N-gons under the semidiscrete second-order evolution equation.
Moreover, we conclude the convexity preserving property during the flow, and from taking a
convergent subsequence, the asymptotic limit is an equilibrium configuration of the evolution
equation.
