In this paper, we study the various cylindrical so-
lutions (cosmic strings) in gravity’s rainbow scenario. In
particular, we calculate the gravitational field equations cor-
responding to energy-dependent background. Further, we
discuss the possible Kasner, quasi-Kasner and non-Kasner
exact solutions of the field equations. In this framework, we
find that quasi-Kasner solutions cannot be realized in grav-
ity’s rainbow. Assuming only time-dependent metric func-
tions, we also analyse the time-dependent vacuum cosmic
strings in gravity’s rainbow, which are completely different
than the other GR solutions.
