Title: The analysis of singularity for some chemotaxis-fluid systems
Time & Venue: 2026年7月8日（星期三） 14:30-15:30 南楼N208
Abstract: Chemotaxis-fluid systems model the collective motion of bacteria and microorganisms under the influence of chemical signals, oxygen concentration, and fluid flow. These systems display complex nonlinear phenomena such as aggregation, bioconvective plumes, bacterial turbulence, and possible singularity formation. In this talk, I will discuss the analysis of singularities for several chemotaxis-fluid systems. The main topics include suitable weak solutions, local energy inequalities, cancellation structures in energy estimates, and partial regularity results for chemotaxis-Navier-Stokes type systems.
