我们确定的平衡形状的朗缪尔单层域使用广义吉布斯-汤姆森方程。我们得到的扭结域的标度行为与实验观察。我们发现新的形状特征的软物质：dips和quasicusps。软物质表现出两种相反的趋势：由于虚拟纹理缺陷的出现，即使对于非常小的各向异性，它也会产生扭结，并且由于其体积的柔软性，它避免了真正的尖锐奇点。
We determine the equilibrium shapes of Langmuir monolayer domains using a generalized Gibbs-Thomson equation. We obtain kinked domains whose scaling behavior agrees with that experimentally observed. We find new shape features characteristic of soft matter: dips and quasicusps. Soft matter exhibits two antagonistic trends: it gives rise to kinks even for very small anisotropies, due to the appearance of virtual textural defects, and it avoids true sharp singularities, due to the softness of its bulk.
