一类趋化性生物模型行波解的存在性与正则性
The Existence and Regularity of Travelling Wave Solutions in a Biological Model for Chemotaxis
【摘要】 研究了一类趋化性生物模型行波解的存在性和正则性.通过直接计算得到了其行波解存在的充分必要条件;在一定条件下,研究了行波解的正则与非正则的性质;在特殊情形下给出了行波解的显式解.
【Abstract】 We study the existence and regularity of travelling wave solutions in a biological model for chemotaxis.We get the necessary and sufficient conditions for its existence by computing directly.Under some conditions,we study its regularity and irregularity.At last,we get the explicit solutions under some special conditions.
