气泡的几何流动

Geometric Flow of Bubbles

Davide De Biasio, Dieter Lust

摘要:

在这项工作中,我们推导出一类几何流方程的度量标量系统。此后,我们构造他们从一些一般的字符串帧的行动,通过执行体积保持字段的变化和写下相关的梯度流方程。然后,我们考虑上述过程的一些具体实现,将流动方程应用于非平凡的标量气泡和度量气泡解,研究随后的流动行为。

英文摘要:

In this work we derive a class of geometric flow equations for metric-scalar systems. Thereafter, we construct them from some general string frame action by performing volume-preserving fields variations and writing down the associated gradient flow equations. Then, we consider some specific realisations of the above procedure, applying the flow equations to non-trivial scalar bubble and metric bubble solutions, studying the subsequent flow behaviour.
