Explicit Integration of Friedmann's Equation with Nonlinear Equations of State
Shouxin Chen, Gary W. Gibbons, Yisong Yang
This paper is a continuation of our earlier study on the integrability of the Friedmann equations in the light of the Chebyshev theorem. Our main focus will be on a series of impor…
Friedmann's Equations in All Dimensions and Chebyshev's Theorem
Shouxin Chen, Gary W. Gibbons, Yijun Li +1
This short but systematic work demonstrates a link between Chebyshev's theorem and the explicit integration in cosmological time and conformal time of the Friedmann equatio…
Solutions to the Master Equations Governing Fractional Vortices
Chang-Shou Lin, Gabriella Tarantello, Yisong Yang
By means of variational methods, in this paper, we establish sharp existence results for solutions of the master equations governing `fractional multiple vortices.' In the doubly p…
Charged cosmological dust solutions of the coupled Einstein and Maxwell equations
Joel Spruck, Yisong Yang
It is well known through the work of Majumdar, Papapetrou, Hartle, and Hawking that the coupled Einstein and Maxwell equations admit a static multiple blackhole solution representi…
