The Large scale structure in a universe dominated by cold plus hot dark matter

Using numerical simulations, we investigate the large-scale gravitational clustering in a flat universe dominated by cold plus hot dark matter (i,e. Ω O =Ω CDM +Ω HDM +Ω baryon =1). Primordial density fluctuation spectrum is taken to have the Zel'dovich-Harrison form. Three models are studied, with Model I having Ω CDM =0.69, Ω baryon =0.01, and Ω HDM =0.30 in one flavor of neutrinos; Model II having Ω CDM =0.60, Ω baryon =0.10, and Ω HDM =0.30 in one flavor of neutrinos
