Abstract: This paper investigates the existence of a uniform in time L∞ bounded weak entropy solution for the quasilinear parabolicparabolic KellerSegel model with the supercritical diffusion exponent 0 < m < 2  2/d in the multidimensional space ℝd under the condition that the L d(2m)/2 norm of initial data is smaller than a universal constant. Moreover, the weak entropy solution u(x,t) satisfies mass conservation when m > 12/d. We also prove the local existence of weak entropy solutions and a blowup criterion for general L1 ∩ L∞ initial data.
