Performing in a country rife with racism and segregation, the tenor Roland Hayes was the first African American man to reach international fame as a concert performer and one of the few artists who could sell out Town Hall, Carnegie Hall, Symphony Hall, and Covent Garden. His trailblazing career carved the way for a host of African American artists, including Marian Anderson and Paul Robeson. Performing the African American spirituals he was raised on, Hayes's voice was marked with a unique sonority which easily navigated French, German, and Italian art songs. A multiculturalist both on and off the stage, he counted among his friends George Washington Carver, Eleanor Roosevelt, Ezra Pound, Pearl Buck, Dwight Eisenhower, and Langston Hughes. This engaging biography spans the history of Hayes's life and career and the legacy he left behind as a musician and a champion of African American rights. It is an authentic, panoramic portrait of a man who was as complex as the music he performed.

This volume contains the proceedings of the Arizona School of Analysis and Mathematical Physics, held from March 5-9, 2018, at the University of Arizona, Tucson, Arizona. A main goal of this school was to introduce graduate students and postdocs to exciting topics of current research that are both influenced by physical intuition and require the use of cutting-edge mathematics. The articles in this volume reflect recent progress and innovative techniques developed within mathematical physics. Two works investigate spectral gaps of quantum spin systems. Specifically, Abdul-Rahman, Lemm, Lucia, Nachtergaele, and Young consider decorated AKLT models, and Lemm demonstrates a finite-size criterion for $D$-dimensional models. Bachmann, De Roeck, and Fraas summarize a recent proof of the adiabatic theorem, while Bachmann, Bols, De Roeck, and Fraas discuss linear response for interacting Hall insulators. Models on general graphs are the topic of the articles by Fischbacher, on higher spin XXZ, and by Latushkin and Sukhtaiev, on an index theorem for Schrodinger operators. Probabilistic applications are the focus of the articles by DeMuse and Yin, on exponential random graphs, by Saenz, on KPZ universality, and by Stolz, on disordered quantum spin chains. In all, the diversity represented here is a testament to the enthusiasm this rich field of mathematical physics generates.
