The present study deals with locally rotationally symmetric (LRS) Bianchi type II string cosmological models with perfect fluid distribution of matter. We consider two cases: (i) ρ+λ = 0 and (ii) ρ−λ = 0, where ρ and λ are the rest energy density and the tension density of the string cloud, respectively. The physical properties of the models is discussed.
Proučavamo lokalno-rotacijski simetrične (LRS) Bianchijeve kozmološke modele tipa II sa strunama za perfektnu tekućinsku raspodjelu mase. Razmatramo dva slučaja: ρ + λ = 0 i (ii) ρ − λ = 0, gdje su ρ i λ gustoća energije mirovanja odn. gustoća napetosti oblaka struna. Opisujemo također fizikalna svojstva tih modela.
