Title: On some properties of mean field spin glasses

Abstract: Spin glasses are magnetic systems exhibiting both quenched disorder and frustration, and have often been cited as examples of "complex systems." As mathematical objects, they provide several fascinating structures and conjectures. This talk will cover some recent progress in mean field models that include the famous Sherrigton-Kirkpatrick model and the bipartite model. We will focus on properties of the energy landscape and of the functional order parameter. We will explain how these properties help to shed more light in the mysterious and beautiful solution proposed 30 years ago by G. Parisi. Based on joint works with Wei-Kuo Chen.
