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.

DOI: 10.1080/00036811.2018.1469009

Abstract: ABSTRACT The Riemann problem for the isentropic Euler system with the state equation for the extended Chaplygin gas is considered, and the Riemann solutions are constructed completely for all the cases. The limiting relations of… read more here.

DOI: 10.1088/1361-6544/ab5c0a

Abstract: We consider nonholonomic Chaplygin systems and associate to them a $(1,2)$ tensor field on the shape space, that we term the gyroscopic tensor, and that measures the interplay between the non-integrability of the constraint distribution… read more here.

DOI: 10.1134/s0202289319020099

Abstract: We study the original Chaplygin gas model in the context of Randall-Sundrum type-II braneworld with a hyperbolic potential. We consider the Chaplygin gas as a candidate for inflation by using the latest data release from… read more here.

DOI: 10.1134/s1560354719050022

Abstract: We consider the $n$-dimensional Chaplygin sphere under the assumption that the mass distribution of the sphere is axisymmetric. We prove that for initial conditions whose angular momentum about the contact point is vertical, the dynamics… read more here.

recommendations! Published in 2019 at "Canadian Journal of Physics"

DOI: 10.1139/cjp-2017-1008

Abstract: In this work, we have considered the Friedmann-Robertson-Walker (FRW) model of the universe where bounce occurs and the universe is filled with Generalized Cosmic Chaplygin Gas (GCCG) or Variable Modified Chaplygin Gas (VMCG). We have… read more here.
