摘要

通过经典分析，我们证明了具有状态参数\(w=-1/3\)方程的宇宙介质中的引力波可以遵循类伦敦方程，这意味着某些引力波解在某些波长下呈现衰减。这种情形与宇宙弦宇宙论相对应，在引力波传播过程中产生了衰减时间尺度。我们讨论了这些解如何对可以传播的波的波长施加限制，这取决于空间曲率的类型和这种宇宙学类型的能量密度内容。

London-Like Tensor Modes of Gravitational Waves in Cosmic String Cosmology

From a classical analysis, we show that gravitational waves in a cosmological medium with the equation of state parameter \(w=-1/3\) can follow a London-like equation, implying that some gravitational wave solutions present a decay for certain wavelengths. This scenario, corresponding to a cosmic string cosmology, induces an attenuation temporal scale on the gravitational wave propagation. We discuss on how these solutions impose a limit on the wavelength of the waves that can propagate, which depends on the type of spatial curvature and the energy density content of this type of cosmology.

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
