AbstractLetD:= {γ∈C3 ( $$mathbb{R},{ ext{ }}mathbb{R}$$ 3)∣γ(s) = γ(s+1),∣ $$dot gamma $$ ∣≡1 γ([0,1])为简单闭曲线}。在本文中,我们证明了存在使泛函最小的γ∈D $$E_{gamma 0} left( gamma ight): = int_0^1 {left| {ddot gamma left( s ight) - ddot gamma _0 left( s ight)} ight|^2 } ds + $$ + a(边界为γ([0,1])的面积最小化曲面),如果a∈(0,∞),则选择γ0∈D。其中,若a∈(0,∞),则选取γ0∈D。
AbstractLetD:= {γ ∈ C3 ( $$mathbb{R},{ ext{ }}mathbb{R}$$ 3) ∣ γ (s) = γ(s+1), ∣ $$dot gamma $$ ∣ ≡ 1 γ ([0,1]) is simple closed curve}.In this paper we show that there is γ ∈ D which minimizes the functional $$E_{gamma 0} left( gamma ight): = int_0^1 {left| {ddot gamma left( s ight) - ddot gamma _0 left( s ight)} ight|^2 } ds + $$ + a(area minimizing surface with boundary γ([0,1])), γ0 ∈ D if a ∈ (0,∞) is suitably chosen.where γ0 ∈ D if a ∈ (0, ∞) is suitably chosen.
