Free Download Geodesic Beams in Eigenfunction Analysis English | 2023 | ISBN: 3031315855 | 183 Pages | PDF EPUB (True) | 15 MB This book discusses the modern theory of Laplace eigenfunctions through the lens of a new tool called geodesic beams. The authors provide a brief introduction to the theory of Laplace eigenfunctions followed by an accessible treatment of geodesic beams and their applications to sup norm estimates, L^p estimates, averages, and Weyl laws. Geodesic beams have proven to be
