标题： Structure Formation in the Universe from Texture Induced Fluctuation

摘要： 这封信的主题是拓扑缺陷的结构形成。 我们首先提出了一组部分新颖、完全局部且规范不变的扰动方程系统，用于处理由拓扑缺陷（或其他类型的种子）引起的微波背景和暗物质涨落。 我们通过将其应用于织构情景来展示这种处理方式非常适合线性数值分析结构形成。 我们的数值结果涵盖了比以往研究更大的动态范围，并且具有互补性，因为我们使用了截然不同的方法。 显示英文摘要

摘要： The topic of this letter is structure formation with topological defects. We first present a partially new, fully local and gauge invariant system of perturbation equations to treat microwave background and dark matter fluctuations induced by topological defects (or any other type of seeds). We show that this treatment is extremly well suited for linear numerical analysis of structure formation by applying it to the texture scenario. Our numerical results cover a larger dynamical range than previous investigations and are complementary since we use substantially different methods.
