Abstract

We prove weak and vague convergence results for spectral shift functions associated with self-adjoint one-dimensional Schr\"odinger operators on intervals of the form $(-\ell,\ell)$ with periodic boundary conditions to the full-line spectral shift function in the infinite volume limit $\ell\to \infty$. The approach employed relies on the use of a Krein-type resolvent identity to relate the resolvent of the operator with periodic boundary conditions to the corresponding operator with Dirichlet boundary conditions in combination with various operator theoretic facts.

Acknowledgments

I am indebted to my advisor, Roger Nichols, for the help he provided me in completing this thesis. I am extremely lucky to have a professor as patient and knowledgable as he is. I thank my mom, Denise Murphy, for being a great mother. I also thank Doug and Nancy Murphy for believing in me. I also thank my siblings, Ashley and Thomas, for always being there for me. Also, I thank all my friends, family, professors, teachers, and coaches that have made me who I am today. I would like to thank the members of my committee, Drs. Barioli, van der Merwe, and Wang for their advice and encouragement.
