图上的NLS基态

NLS ground states on graphs

Riccardo Adami, Enrico Serra, Paolo Tilli

摘要:

研究了度规图上次临界非线性最小二乘能量基态的存在性。特别地,我们找到了一个保证基态不存在的拓扑假设,并给出了一个不满足该假设而基态确实存在的例子。为了得到的结果,我们引入了一个新的重排技术,适用于它所适用的图形。由于这种技术,通过方便地混合对称和单调重排过程,提高了重排函数的能级。

英文摘要:

We investigate the existence of ground states for the subcritical NLS energy on metric graphs. In particular, we find out a topological assumption that guarantees the nonexistence of ground states, and give an example in which the assumption is not fulfilled and ground states actually exist. In order to obtain the result, we introduce a new rearrangement technique, adapted to the graph where it applies. Owing to such a technique, the energy level of the rearranged function is improved by conveniently mixing the symmetric and monotone rearrangement procedures.
