These one-week conferences are held approximately every four years in the summer. They focus on seminal concepts in the forefront of mathematics and are made possible by the generous support of a fund established by Dr. and Mrs. Carrol V. Newsom in honor of the memory of John von Neumann.

Organized organized by **Motohico Mulase **(Chair), University of California, Davis;** Bertrand Eynard**, Institut de Physique Théorique, CEA; and **Chiu-Chu Melissa Liu**, Columbia University, New York. It reflected the recent extremely rapid and rich developments in the emerging research field that is generally known as topological recursion. It had its origin in random matrix theory, and also in the work of Mirzakhani on the volume of the moduli space of hyperbolic surfaces. It had played a fundamental role in connecting seemingly unrelated areas of mathematics, such as matrix models, enumeration of Hurwitz numbers and Grothendieck's dessins d'enfants, Hitchin moduli spaces, the A-polynomials and colored polynomial invariants of knots, Gromov-Witten invariants, the WKB asymptotic analysis of 1-dimensional Schrödinger equations, and the non-Abelian Hodge correspondence. The symposium was planned right at the time when many discoveries and crucial theorems were established, and at the same time, numerous new mysteries were arising.

AMS von Neumann Symposium on *Multimodel and Multialgorithm Coupling for Multiscale Problems*

Organized by **John B. Bell** (chair), Lawrence Berkeley National Laboratory; **Alejandro L. Garcia**, San Jose State University; and **Francis Alexander**, Los Alamos National Laboratory. Multiscale problems are of increasing importance in the fields of physics, biology, chemistry, fluid dynamics, environmental science, materials science, geophysics, and all branches of engineering. The symposium brought groups together in four key areas (fluids, solids, earth sciences, and molecular dynamics) and enabled applied mathematicians and scientists to discuss current practices and future research directions in the development of hybrid methodologies for multiscale phenomena.
