报告摘要:

This talk is concerned with a cross-diffusion tumor invasion model with double-taxis effect. We first investigate the global existence of classical solutions in two dimensional space, some new estimation techniques are adopted to overcome the difficulties brought by double-taxis. Subsequently, we pay our attention to the stability of the equilibria. We first consider the stability of a semi trivial equilibrium, and give sufficient conditions to ensure its global asymptotic stability or instability. While, for the other equilibria, the stability analysis is complicated even for some special cases, and both the double chemotactic coefficients will affect the stability of the solution.
