   目: Blow-up and global existence of attraction-repulsion chemotaxis systems


报告人:李玉祥 教授  东南大学


  要: We consider an attraction-repulsion chemotaxis system under homogeneous Neumann boundary conditions in a smooth bounded domain in . First we study the system without logistic term, obtaining the finite-time blowup of nonradial solutions. Secondly, under a growth restriction on logistic source and suitable assumptions on the positive parameters, we show the existence of global bounded classical solutions. The global weak solution is also constructed if the logistic damping effect is rather mild. Furthermore, we obtain the asymptotic behavior of solutions.
