Scientific paper

Singularity-free Robertson-Walker cosmological models (RWCM) are developed by considering the cosmic matter as composed of an interacting viscous fluid (with zero bulk viscosity) and a massive scalar (meson) field. Solutions are obtained for two different cases, viz., when the Hubble's parameter H is epoch independent and when H is epoch dependent. A solution corresponding to RWCM with only the massive scalar field as the matter content is also presented. The essential physical behavior of the models developed are discussed in detail.
