标题： Cadabra and Python algorithms in General Relativity and Cosmology II: Gravitational Waves

摘要： 计算机代数系统（CASs）如Cadabra软件在物理学及相关领域的广泛研究活动中起着重要作用。 我们展示了如何将Cadabra语言轻松地实现于已建立的Python编程框架中，从而获得卓越的灵活性和定制性，以解决广义相对论中的张量扰动问题。 我们获得了一个有效的算法，用于分解到度规任何扰动阶数的张量量。 我们的代码特性通过讨论与一阶/高阶引力波相关研究活动中的具体计算问题进行测试。 显示英文摘要

摘要： Computer Algebra Systems (CASs) like Cadabra Software play a prominent role in a wide range of research activities in physics and related fields. We show how Cadabra language is easily implemented in the well established Python programming framework, gaining excellent flexibility and customization to address the issue of tensor perturbations in General Relativity. We obtain a performing algorithm to decompose tensorial quantities up to any perturbative order of the metric. The features of our code are tested by discussing some concrete computational issues in research activities related to first/higher-order gravitational waves.
