报告摘要:This talk is mainly concerned with a spatially two-dimensional version of a chemotaxis system with logistic cell proliferation and death, for a singular tactic response of standard logarithmic type, and with interaction with a surrounding incompressible fluid through transport and buoyancy. Systems of this form are of significant relevance to the understanding of chemotaxis-fluid interaction, but the rigorous knowledge of their qualitative properties is yet far from complete even in the two-dimensional setting. In this direction, using the conditional energy functional method, we will provide some interesting contributions by establishing results on global boundedness, and especially on large timestabilization toward homogeneous equilibria, under mild assumptions on the initial data and appropriate conditions on the strength of the damping death effects. This is a joint work with Peter Y.~H.~Pang and Jingxue Yin.
