Bianchi type-III string cosmological models are investigated in the presence of string fluid as a source of matter in the framework of Lyra’s geometry. It is observed that the models start with singular state and evolve continuously as t → ∞. It is found that, in all cases, the displacement vector β(t) is a decreasing function of time analogous to the behaviour of the cosmological constant Λ. The physical and geometrical aspects of the models are also discussed.Istražujemo Bianchijeve kozmološke modele III vrste u prisustvu tekućine struna kao izvora tvari u okviru Lyrine geometrije. Nalazimo da prema modelima svemir počinje sa singularnim stanjem i razvija se postepeno kako t → ∞. U svim slučajevima smo našli da je vektor posmika β(t) opad...
