%X 摘要： 研究了一类Keller-Segel型交叉扩散方程组的柯西问题。 利用Green函数的方法, 得到带有小初值的柯西问题解的逐点估计, 以及解在W s,p(Rn)空间中的衰减性质。<br>Abstract: We consider the Canchy problem for a class of Keller-Segel equations with cross-diffusion. By utilizing the method of Greens function, we obtain the pointwise estimates of solutions to the Cauchy problem for small initial data, and the W s,p(1≤p≤∞) decay properties of solutions
