In this talk, we will consider properties of solutions for degenerate Keller-Segel(K-S) equations, which include the degenerate parabolic-elliptic K-S model and the degenerate parabolic-parabolic K-S model. For the parabolic-elliptic case, we will clarify the important relation between the Hardy-Littlewood-Sobolev inequality and the sharp condition for the global existence and blow-up. For the parabolic-parabolic case, a closed relation between the Sobolev inequality vs the sharp condition for the global existence will be stated. Moreover, we will show some results on the L1-bound and uniqueness of weak solutions for degenerate Keller-Segel equations.
