本文研究了一维趋化性模型稳态解的定性性质,该模型由Cieślak (2007) [1], Painter和Hillen (2002) [12], Zhang和Zheng(2013)[19]引入,用于模拟体积填充效应。更准确地说,我们将对稳态解的存在与否进行分类,如果存在,则根据间隔长度、细胞密度的空间平均值和趋化系数对稳态解的个数进行分类。这些结果为生物参数如何影响图案形成提供了见解。特别是,我们的结果表明,对于一般的参数类,最多有有限多个非平凡模式。
In this paper, we investigate the qualitative properties of steady-state solutions for a 1-D chemotaxis model, which was introduced by Cieślak (2007)  [1], Painter and Hillen (2002)  [12], and Zhang and Zheng (2013)  [19] to model the volume-filling effect. More precisely, we will classify the existence or nonexistence of steady-state solutions, and if exist, the number of steady-state solutions based on the interval length, the spatial average of cell density and the chemotactic coefficient. These results provide insights on how the biological parameters affect pattern formation. In particular, our results indicate that there are at most finitely many non-trivial patterns for a generic class of parameters.
