Bianchi-IX string cosmological model in Lyra geometry
F Rahaman S Chakraborty N Begum M Hossain M Kalam
A class of cosmological solutions of massive strings for the Bianchi-IX space-time are obtained within the framework of Lyra geometry. Various physical and kinematical properties of the models are discussed

Higher dimensional homogeneous cosmology in Lyra geometry
F Rahaman S Das N Begum M Hossain
Assuming a homogeneous perfect fluid with
ρ =ρ(t) andp =p(t) , we have obtained exact solutions for cosmological models in higher-dimension based on Lyra geometry. Depending on the form of metric chosen, the model is similar to FRW type. The explicit solutions of the scale factor are found via the assumption of an equation of statep =mρ , where m is a constant. Some astrophysical parameters are also calculated.
