recommendations! Published in 2018 at "Acta Applicandae Mathematicae"

DOI: 10.1007/s10440-017-0135-0

Abstract: In this paper, we mainly study the interactions of the elementary waves of the Aw–Rascle model for the generalized Chaplygin gas. With the characteristic analysis method, the solutions are obtained constructively when the initial data… read more here.

DOI: 10.1007/s12648-017-1126-8

Abstract: Cosmological model with viscous generalized Chaplygin gas (in short, VGCG) is considered here to determine observational constraints on its equation of state parameters (in short, EoS) from background data. These data consists of $$H(z)-z$$H(z)-z (OHD)… read more here.

DOI: 10.1007/s40840-020-01003-9

Abstract: The exact Riemann solutions for a macroscopic production model under the equation of state given by the Chaplygin gas are solved explicitly for all possible Riemann initial data. It is discovered interestingly that a composite… read more here.

DOI: 10.1007/s40840-021-01133-8

Abstract: The exact solutions to the Riemann problem for an inhomogeneous extended Chaplygin gas equations with friction are constructed explicitly. Compared to the homogeneous system, the Riemann solutions for the inhomogeneous one are no longer self-similar.… read more here.

Sign Up to like & get
recommendations! Published in 2019 at "Journal of Mathematical Physics"

DOI: 10.1063/1.5108701

Abstract: The so-called Cargo-LeRoux model is a hyperbolic system of conservation laws derived from the Euler equations with a constant gravity. This paper is concerned with such a model for an isentropic Chaplygin gas. The Riemann… read more here.

DOI: 10.1088/1475-7516/2023/04/052

Abstract: The fact that Einstein's equations connect the space-time geometry to the total matter content of the cosmic substratum, but not to individual contributions of the matter species, can be translated into a degeneracy in the… read more here.
