Variable viscous generalized cosmic Chaplygin gas cosmology in presence of the cosmological constant and space curvature

Abstract

Variable viscous generalized cosmic Chaplygin gas (GCCG) was constructed in the presence of cosmological constant and space curvature. Using the numerical analysis we find behavior of some cosmological quantities such as Hubble and deceleration parameters. Observational data is used to fix solution and stability of model is discussed.
