About this event
Izak Oltman from Northwestern University presents a talk on the discrete Mathieu operator. He describes the spectrum of a non-self-adjoint version of Harper's equation using exact WKB methods. The session includes joint work with Frédéric Klopp and explains proof techniques for analytic finite difference equations.

Speaker: Izak Oltman (Northwestern University) Title: The Spectrum of the Discrete Mathieu Operator with Non-Real Coupling Abstract: In this talk, I will describe the spectrum of a non-self-adjoint version of the periodic Harper’s equation. One example of this is the so-called Scottish Flag Operator. A description of the spectrum relies on exact WKB methods to approximate solutions to analytic finite difference equations. I will motivate the study of such operators, describe the main ideas of the proof, and explain the exact WKB techniques that are used. This is joint work with Frédéric Klopp.
