形态发生素输运模型II

A model of morphogen transport II

Marcin Małogrosz

摘要:

分析了一个由两个反应扩散型演化偏微分方程和三个矩形区域上的常微分方程组成的形态素输运模型。我们证明了该问题是全局适定的,并且当矩形的宽度趋于零时,相应的解收敛到该系列第一篇论文中分析的一维系统的唯一解。在分析中的主要困难源于存在一个奇异的源项-一个狄拉克三角洲结合没有平滑效果的常微分方程的系统的一部分。

英文摘要:

A model of morphogen transport consisting of two evolutionary PDEs of reaction-diffusion type and three ODEs posed on a rectangular domain is analysed. We prove that the problem is globally well-posed and that the corresponding solutions converge, as the width of the rectangle tends to zero, to the unique solution of the one dimensional system which was analyzed in the first paper of the series. Main difficulties in the analysis stem from the presence of a singular source term - a Dirac Delta combined with no smoothing effect in the ODE part of the system.
