摘要:

本文研究一类半线性高阶抛物型方程组的Cauchy问题。通过建立高阶抛物型方程组的所谓“比较原理”,利用Schauder不动点理论和试验函数等方法,证明了该问题在慢衰减初值条件下解的整体性存在性与不存在性。

This paper concerns with the Cauchy problem of a higher-order parobolic system. By constructing a so called “comparison principle”of the higher-order parobolic system and utilizing Schauder fixed point theorem and the test function method, we prove the existence and nonexistence of global solutions to such a problem with slow decay initial data.
