主要研究一维生物趋化模型的初边值问题. 在L2范数充分小, H2范数不作任何约束的情况下, 通过构造一个非负凸熵, 再作它的L2能量估计、一阶能量估计、二阶能量估计, 从而得到初边值问题解的整体存在性和指数衰减估计.

In this paper, we mainly study the initial boundary value problem of one-dimensional biological chemotaxis model. In the case of sufficiently small L2-norm, and H2-norm without any constraints, by constructing a nonnegative convex entropy,and then making its L2-energy estimates, first-order and second-order energy estimates, we get the global existence and exponential decay estimates of solution to the initial boundary value problem.
