摘要 In this paper,the Cauchy problem of the classical Keller-Segel chemotaxis model with initial data of large mass is considered.By the Green’s function method and scaling technique,we prove that if‖u0‖■‖u0‖■ and κ‖Δv0‖Lp are less than some constant,then the problem always admits a unique global classical solution,even when the initial mass‖u0‖L1 is large.Moreover,the decay rates of the classical solution are also obtained.
