摘要
主要研究一维生物趋化模型的初边值问题.在L^2范数充分小,H^2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2L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 L-2-norm, and H-2-norm without any constraints, by constructing a nonnegative convex entropy, and then making its L-2-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.
