跳跃生成元的预解界和非局部薛定谔算子的基态渐近性

Resolvent bounds for jump generators and ground state asymptotics for nonlocal Schrödinger operators

Yuri Kondratiev, Stanislav Molchanov, Andrey Piatnitski, Elena Zhizhina

摘要:

本文讨论了具有卷积核的跳跃生成器。假设核衰减指数或多项式,我们证明了一些下限和上限的预解式等运营商。我们考虑这些结果的两个应用。首先,我们得到了跳跃生成元的主本征函数的逐点估计,这些跳跃生成元受紧支撑势(所谓的非局部薛定谔算子)的扰动。然后我们考虑相应的非齐次发展方程的柯西问题,并研究其解的性质。

英文摘要:

The paper deals with jump generators with a convolution kernel. Assuming that the kernel decays either exponentially or polynomially we prove a number of lower and upper bounds for the resolvent of such operators. We consider two applications of these results. First we obtain pointwise estimates for principal eigenfunction of jump generators perturbed by a compactly supported potential (so-called nonlocal Schrödinger operators). Then we consider the Cauchy problem for the corresponding inhomogeneous evolution equations and study the behaviour of its solutions.
