摘要

本文描述了在标度为 1 的曲面上局部存在三角势的薛定谔方程的考希问题解的半经典渐近学。带有三角势的薛定谔算子是利用扩展理论定义的，并通过该表面上的边界条件加以规定。初始条件选择了窄峰的形式，它是一个高斯包，定位在任意维度表面的一个小邻域内，并沿着它快速振荡。马斯洛夫复胚方法用于构建渐近线。描述了各向同性流形与德尔塔势相互作用的复胚芽的反射。 doi 10.1134/s1061920824030142

Reconstruction of Maslov’s Complex Germ in the Cauchy Problem for the Schrödinger Equation with a Delta Potential Localized on a Hypersurface

The semiclassical asymptotics of the solution of the Cauchy problem for the Schrödinger equation with a delta potential localized on a surface of codimension 1 is described. The Schrödinger operator with a delta potential is defined using extension theory and specified by boundary conditions on this surface. The initial conditions are chosen in the form of a narrow peak, which is a Gaussian packet, localized in a small neighborhood of a surface of arbitrary dimension, and oscillating rapidly along it. The Maslov complex germ method is used to construct the asymptotics. The reflection of an isotropic manifold with a complex germ interacting with the delta potential is described.

期刊介绍： Russian Journal of Mathematical Physics is a peer-reviewed periodical that deals with the full range of topics subsumed by that discipline, which lies at the foundation of much of contemporary science. Thus, in addition to mathematical physics per se, the journal coverage includes, but is not limited to, functional analysis, linear and nonlinear partial differential equations, algebras, quantization, quantum field theory, modern differential and algebraic geometry and topology, representations of Lie groups, calculus of variations, asymptotic methods, random process theory, dynamical systems, and control theory.
