我们给出了IIA型F弦极化成圆柱D2膜的矩阵和超引力描述。当RR四形式场强F_4以超对称方式（具有4个超荷）打开时，解的完整分析揭示了对于某些分数强度的扰动存在F1 -> D2极化（Caesar）的模空间，而对于所有其他强度的扰动不存在任何极化（nihil）。这是一个非常有趣的现象，我们只能推测其物理含义。在极化的矩阵描述中，我们使用非阿贝尔的Born-Infeld作用在极端的制度，其中的领域是远远大于1。我们得到的结果的有效性，提供了一个直接确认这一行动，虽然它不确认或反驳对称化的痕迹规定。
We give matrix and supergravity descriptions of type IIA F-strings polarizing into cylindrical D2 branes. When a RR four-form field strength F_4 is turned on in a supersymmetric fashion (with 4 supercharges), a complete analysis of the solutions reveals the existence of a moduli space of F1 -> D2 polarizations (Caesar) for some fractional strengths of the perturbation, and of no polarization whatsoever (nihil) for all other strengths of the perturbation. This is a very intriguing phenomenon, whose physical implications we can only speculate about. In the matrix description of the polarization we use the Non-Abelian Born-Infeld action in an extreme regime, where the commutators of the fields are much larger than 1. The validity of the results we obtain, provides a direct confirmation of this action, although is does not confirm or disprove the symmetrized trace prescription.
