标题： Superfluid Rayleigh-Plesset extension of FLRW cosmology

摘要： 基于超流体氦-4中多电子气泡的Rayleigh-Plesset动力学的类比，我们考虑了宇宙尺度因子的逆的立方和六次方的宇宙学FLRW演化方程。 在零宇宙学常数以及无粘性项的情况下，并使用Sundman时间作为参数，我们给出了宇宙尺度因子的参数解，这些解以Weierstrass椭圆函数的有理表达式及其特殊和退化情况表示。 显示英文摘要

摘要： Guided by the analogy with the Rayleigh-Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and sixth powers of the inverse of the scale factor of the universe. For zero cosmological constant along with the absence of viscous terms, and using the Sundman time as parameter, we present parametric solutions for the scale factor of the universe in terms of rational expressions of Weierstrass elliptic functions and special and degenerate cases thereof.
