Cayley树上广义薛定谔方程的周期解

Periodic Solutions of Generalized Schrödinger Equations on Cayley Trees

Fumio Hiroshima, József Lörinczi, Utkir Rozikov

摘要:

本文在Cayley树上定义了一个具有任意实幂的离散广义Laplacian。这个拉普拉斯算子用于定义树上的离散广义薛定谔算子。详细研究了指数为$0 < α< 2$的离散分数阶Schr dinger算子的情形,并给出了相应分数阶薛定谔方程的周期解.这种周期性取决于凯莱树的群表示的子群。对于任意有限指数子群,我们给出了薛定谔算子存在周期解的特征值的一个判据。对于指数为无穷大的正规子群,我们描述了一类广泛的周期解。

英文摘要:

In this paper we define a discrete generalized Laplacian with arbitrary real power on a Cayley tree. This Laplacian is used to define a discrete generalized Schrödinger operator on the tree. The case discrete fractional Schrödinger operators with index $0 < α< 2$ is considered in detail, and periodic solutions of the corresponding fractional Schrödinger equations are described. This periodicity depends on a subgroup of a group representation of the Cayley tree. For any subgroup of finite index we give a criterion for eigenvalues of the Schrödinger operator under which periodic solutions exist. For a normal subgroup of infinite index we describe a wide class of periodic solutions.
