树上发展方程解的存在唯一性和衰减率

Existence, uniqueness and decay rates for evolution equations on trees

Leandro M. Del Pezzo, Carolina A. Mosquera, Julio D. Rossi

摘要:

研究了有向树上由平均算子控制的发展方程,证明了解的存在唯一性。此外,我们发现的初始条件,使我们能够找到的渐近衰减率的解决方案作为$t\to \infty$的条件。事实证明,这个衰减率是不均匀的,它强烈地依赖于初始条件如何在树中下降到零。

英文摘要:

We study evolution equations governed by an averaging operator on a directed tree, showing existence and uniqueness of solutions. In addition we find conditions of the initial condition that allows us to find the asymptotic decay rate of the solutions as $t\to \infty$. It turns out that this decay rate is not uniform, it strongly depends on how the initial condition goes to zero as one goes down in the tree.
