# On the Existence and Uniqueness of Self-Adjoint Realizations of Discrete (Magnetic) Schrödinger Operators

@inproceedings{Schmidt2020OnTE, title={On the Existence and Uniqueness of Self-Adjoint Realizations of Discrete (Magnetic) Schr{\"o}dinger Operators}, author={Marcel Schmidt}, year={2020} }

Discrete Laplacians and discrete magnetic Schrödinger operators feature in many different areas of mathematics. They are used in combinatorics and computer science, appear as discretizations of (pseudo-)differential operators on Riemannian manifolds, serve as toy models for Hamiltonians in mathematical physics and play an important role in the study of random walks just to name a few. Even though discrete operators are used for very different means, their basic structure is always the same…
