Ostrowski Prize to Professor Hong Wang
Professor Hong Wang received the 2025 Ostrowski Prize on 21 November 2025, followed by a prize lecture by the recipient.

The 2025 Ostrowski Prize will be awarded to Hong Wang (IHES and NYU) for her contributions to harmonic analysis and her recent solution of the Kakeya conjecture in dimension 3 with Joshua Zahl, with the following program:
- Laudation speech by Larry Guth (MIT)
- Presentation of the prize by Helmut Harbrecht (President of the Ostrowski Foundation)
- Prize lecture by Hong Wang.
Title: Restriction theory and projection theorems.
Abstract: Restriction theory studies functions whose Fourier transforms are supported on some curved manifold in R^n (for example, solutions to the linear Schrodinger equation or to the wave equation). Projection theorems study the Hausdorff dimension of fractal sets under orthogonal projections from R^n to its subspaces. We will survey some recent works in both fields and discuss their interactions.
The department and the Ostrowski Foundation host a reception after the ceremony in the southern end of "Vandrehallen".
The event is open and everyone is welcome to attend.
In connection with the prize ceremony there will be two events the day before:
- Special analysis seminar Projection theorems and equidistributions by Elon Lindenstrauss (Hebrew University, Fields medal, 2010), Thursday Nov. 20, 12:05-13:00 in Aud. 3 (sandwiches are served)
- Department colloquium Bounds for the number of zeros of the Riemann zeta functions in strips by Larry Guth (MIT), Thursday Nov. 20, 15:15-16:15 in Aud. 1. Cakes (from Anderson Bakery!), tea and coffee is served in front of Aud 1 from 14:50.
