报告摘要：

    This talk considers a parabolic-elliptic chemotaxis system with weakly singular sensitivity and logistic source. We give quantitative estimate of the upper bound for u with respect to the coefficient μ after some time and then obtain the long-time behavior of solution by dealing with the corresponding transformed non-singular chemotaxis system, without establishing the uniformly positive bound for v from below.
