The Antonio Ambrosetti medal is awarded in memory of Antonio Ambrosetti, who was one of the first three Professors at SISSA since the foundation of the School in 1980, then appointed Professor at Scuola Normale Superiore in the years 1986-1998, and subsequently again Professor at SISSA since 1998 to 2012. The Medal is awarded by SISSA, with the support of Scuola Normale Superiore, Accademia Nazionale dei Lincei, Unione Matematica Italiana (UMI). Antonio Ambrosetti made several groundbreaking contributions to mathematical analysis, ranging from critical point theory, variational and topological methods, bifurcation theory, with applications in Hamiltonian systems and geometry. He is one of the founders with Giovanni Prodi of the Italian school of nonlinear analysis, with far-reaching influences in various areas of Mathematics. Simple and powerful geometric ideas standing at the basis of his approach allowed remarkable, and sometimes unexpected developments with numerous applications in differential equations. The medal recognizes exceptionally promising young researchers who have already made outstanding contributions to the fields of nonlinear analysis.
The Ambrosetti medal is awarded every two years starting from 2021.

The medal has been awarded the 21 November 2025 during the conference "New frontiers in nonlinear analysis and differential equations “ to
- Yu Deng (University of Chicago), for innovative contributions to the theory of nonlinear evolution equations and the understanding of the relations among Newtonian models of particle interactions, kinetic equations and the macroscopic description of fluid dynamics, as proposed by the long-standing open Hilbert's sixth problem. He has been able to combine strong analytical methods and ideas from other fields, such as probability theory, to obtain remarkable progress;
- Riccardo Montalto (University of Milano) for numerous and significant contributions to KAM theory for water wave and other model fluid equations, including those of Navier-Stokes and Euler, in both 2 and 3 dimensions, and including fluids behaving quasi-periodically in space. These novel results are based on pseudo-differential calculus and Nash-Moser type bifurcation theorems, and have had a profound impact on the field;
- Hong Wang (New York University and IHES) for her outstanding and pioneering contributions to harmonic analysis and related fields. Her innovative methods, including the introduction of new structural insights into wave packet analysis, have led to landmark results that illuminate central problems in analysis and its connections with number theory and geometric measure theory. Her recent work on sticky Kakeya sets has opened new directions with profound implications.
