General Physics 2013-03-12 v1

Abstract

In this latter author would like to consider interaction between a dark energy based on Generalized Uncertainty Principle (GUP) and a Dark Matter described by effective EoS: P=(γ1)ρ+p0+ωHH+ωH2H2+ωdHH˙P = (\gamma-1)\rho+p_{0}+\omega_{H}H+\omega_{H2}H^{2}+\omega_{dH}\dot{H} [1]-[3], which could be interpreted as a modification concerning to the some interaction between fluid P=(γ1)ρP=(\gamma-1)\rho with different components of the Darkness of the Universe. Two types of interaction, called sign-changeable, Q=q(3Hbρm+βρ˙m)Q=q(3Hb\rho_{m}+\beta\dot{\rho}_{m}) [4],[5] and Q=3Hbρm+βρ˙mQ=3Hb\rho_{m}+\beta\dot{\rho}_{m} are considered. EoS parameter of the mixture ωtot\omega_{tot} are investigated. Statefinder diagnostics provided also.
