Abstract. In this paper, we discuss Cosmological models based on Lyra's geometry in the presence of particle creation. The effect of variable deceleration parameter on the displacement field (β) and energy density (ρ) has been inspected and exact solution is obtained for FRW model for a specific form of particle creation function.
