Title: Self-adjoint extension schemes and modern applications to quantum Hamiltonians
Title（参考訳）: 自己共役拡張スキームと量子ハミルトンへの応用
Authors: Matteo Gallone and Alessandro Michelangeli
Abstract要約: モノグラフは、過去数年間、両方の著者が、抽象演算子理論と量子力学への応用の両方において中心的な主題について行った、学部・大学院・セミナーの以前の講義ノートから、改訂および拡張された資料を含んでいる。数種類のモデルが議論され、これは今日、数学物理学への新たな関心または新たな関心を受けており、特に、ある興味を持つ作用素を自己随伴的に実現するという観点から考察されている。

Abstract: This monograph contains revised and enlarged materials from previous lecture notes of undergraduate and graduate courses and seminars delivered by both authors over the last years on a subject that is central both in abstract operator theory and in applications to quantum mechanics: to decide whether a given densely defined and symmetric operator on Hilbert space admits a unique self-adjoint realisation, namely its operator closure, or whether instead it admits an infinite multiplicity of distinct self-adjoint extensions, and in the latter case to classify them and characterise their main features (operator and quadratic form domains, spectrum, etc.) This is at the same time a very classical, well established field, corresponding to the first part of the monograph, and a territory of novel, modern applications, a selection of which, obviously subjective to some extent, but also driven by a pedagogical criterion, is presented in depth in the second part. A number of models are discussed, which are receiving today new or renewed interest in mathematical physics, in particular from the point of view of realising certain operators of interests self-adjointly, classifying their self-adjoint extensions as actual quantum Hamiltonians, studying their spectral and scattering properties, and the like, but also from the point of view of intermediate technical questions that have theoretical interest per se, such as characterising the corresponding operator closures and adjoints.
