# Canzani Beaming Over New Book

Professor Yaiza Canzani and her co-author Jeff Galkowski just dropped their new book: *Geodesic beams in eigenfunction analysis. *Yaiza and Jeff have pioneered methods for studying Laplace eigenfunction concentration by utilizing an intrinsic link between the behavior of eigenfunctions and geodesic flow, a deep reflection of the correspondence between quantum and classical dynamics. From the author’s description: “Geodesic beams have proven to be a valuable tool in the study of Laplace eigenfunctions, but their treatment is currently spread through a variety of rather technical papers. The authors present a treatment of these tools that is accessible to a wider audience of mathematicians. Readers will gain an introduction to geodesic beams and the modern theory of Laplace eigenfunctions, which will enable them to understand the cutting edge aspects of this theory.”

Congratulations Yaiza!
