摘要:

该文研究了一类由曲率控制细胞和组织生长演化的Cauchy问题, 根据支撑函数的定义, 将拟线性退化的演化方程转化成一类非齐次拟线性双曲方程组. 进一步通过对拟线性双曲方程组的解的先验估计, 证明了该双曲曲率流Cauchy问题经典解的生命跨度.

关键词: 曲率控制下细胞和组织的演化, 非齐次拟线性双曲方程组, 先验估计, 生命跨度

Abstract:

In this paper, We consider Cauchy problem for the evolution of cells and tissue during curvature-controlled growth. By the definition of Riemann invariants, the evolution equation can be rewritten as a non-homogeneous quasilinear hyperbolic system. the lifespan of classical solution to the initial value problem is given by a priori estimation of the solution of the quasilinear hyperbolic system.

Key words: The evolution of cells and tissue during curvature-controlled growth, Non-homogeneous quasilinear hyperbolic system, Priori estimation, Lifespan
