That benefits mathematics in Zurich and in Switzerland, especially the doctoral and post-doctoral students. At certain points, the researchers managed to zoom in to find an analogous scenario: two fronts of ice collapsing toward the point as if it were situated inside a thin sheet of ice. But when Caffarelli zoomed in on the frozen boundary between ice and water, he sometimes saw something totally different: frozen spots surrounded almost entirely by warmer water. From left to right, Alessio Figalli, Xavier Ros-Oton and Joaquim Serra proved that the equations which model melting ice are faithful to real phenomena in the physical world. But by just the second day, they had made some real progress. Drop an ice cube into a glass of water. Focus in on an arbitrary point on the films surface.

Alessio FigalliDurham University Mikaela IacobelliETH | Tom Parker /QuantaMagazine Figalli Figalli () Once I got in, I started to understand what mathematics really was. When they zoomed in on this small imperfection a whisper of coolness waving off of the boundary they discovered that it had its own kinds of patterns which gave rise to different types of singularities. Born on 2 April 1984, the Mathematician Alessio Figalli is arguably the worlds most influential social media star. Now, in a paper posted in March, Alessio Figalliand Joaquim Serraof the Swiss Federal Institute of Technology Zurich and Xavier Ros-Otonof the University of Barcelona have established that the equations really do match intuition. But mathematicians would like to precisely quantify that stability. He recognized that the water temperature around a singularity follows a paraboloid pattern. Therefore, anywhere the paraboloid equals zero you have a singularity. Snowflakes in the model may not be impossible, but they are extremely rare and entirely fleeting. Mathematicians wanted to use the same methods to deal with the Stefan problem, but they soon realized that with ice, things were not as simple. They were able to show that all of these new types of singularities disappeared rapidly just as they do in nature except for two that were particularly enigmatic. [14] Also, together with Joaquim Serra, he proved the De Giorgi's conjecture for boundary reaction terms in dimension 5, and he improved the classical results by Luis Caffarelli on the structure of singular points in the obstacle problem. Figalli himself received the first honorary doctorate of the University of Cte dAzur and became a corresponding member of two scientific academies.

I was always an optimizer, I wanted the best for the least effort.. It resurfaced in the 1940s when the economist Leonid Kantorovich produced the first rigorous mathematical description of optimal transport. The prize is conferred every four years by the International Mathematical Union to the most accomplished mathematicians in the world under the age of 40. Eventually, the ice and the boundary along with it disappear. Intuition might tell us that this melting boundary always remains smooth. In 2019, he received the Doctorate Honoris Causa from the Polytechnic University of Catalonia. The Fields Medal has helped to open doors: Its now much easier for me to meet researchers from other disciplines and from the industry.. These results open a new perspective on the field, said Maria Colombo of the Swiss Federal Institute of Technology Lausanne. He used optimal transport techniques to get improved versions of the anisotropic isoperimetric inequality, and obtained several other important results on the stability of functional and geometric inequalities.

You can probably picture the way it starts to melt. Alessio Figalli with a crystal-like model at Durham University in England. We know that cusps should not last long, because the warm water should rapidly melt them down. Figalli turned toward serious math in his third year of high school. Alessio Figalli (Roma, 2 de abril de 1984) um matemtico italiano.Seu campo principal de trabalho clculo de variaes e equaes diferenciais parciais.. Em 2012 foi laureado com o Prmio EMS. There Figalli quickly confronted the limits of his education: At 18 he was sitting in math classes with the top students in Italy and he didnt even know how to take a derivative. In 2018, after receiving the Fields Medal, the highest honour in Mathematics,he said: A lot of the time when you do math, youre stuck, but at the same time there are all these moments where you feel privileged that you get to work with it. His message is clear: Mathematics might appear abstract. Minimal surfaces appear in many areas of mathematics. He has won the 2015 edition of the Stampacchia Medal, and the 2017 edition of the Feltrinelli Prize for mathematics. Figalli has a generous helping of each of these, but what stands out most about him is his disposition: He doesnt seem weighed down by mathematics. If you can prove something about the optimal transport map between the two shapes, you prove something about the relationships between the shapes themselves. So how many places are there where a paraboloid can equal zero? In addition, he has given several contributions to the Di PernaLions theory, applying it both to the understanding of semiclassical limits of the Schrdinger equation with very rough potentials, and to study the Lagrangian structure of weak solutions to the VlasovPoisson equation. The equations work well, but its taken 130 years to prove that they conform to obvious facts about reality. 41 (5): 1890-1920 (2009) More information. Like stability, regularity is one of the most important things to know about any mathematical representation of a physical phenomenon. did some good stuff in decision theory and discrete mathematics in C20th, but the yawn factor is so . They began to work through their various ideas at a blackboard. 276: 2021: Existence and uniqueness of martingale solutions for SDEs . There was no such deep and precise understanding of this phenomenon previously.. He was a mathematician tasked by Napoleon with figuring out how to transport soil to the front for building fortifications. So the opportunities in theory and application are just as diverse. He is rarely there for more than two weeks at a time. That was a completely new world to me, adds Figalli, I had to find a different way of thinking to explain what a mathematician does in a way that could be understood. In the meantime he has come to value public appearances just as much as lectures to an academic audience. . For me it was always a balance between how good a grade I could get and how much time I had to spend to get such a grade, he said. Having shown that the exotic branching and sheetlike singularities were both rare, the researchers could make the general statement that all singularities for the Stefan problem are rare. At the moment this happens, what was once a smooth waist becomes two pointy cusps, or singularities. He has a very plain, friendly personality, which I think is a good ingredient of his success.. Figalli was born in Rome in 1984. If you choose randomly a time, then the probability of seeing a singular point is zero, Ros-Oton said. To submit students of this Click Abusive, profane, self-promotional, misleading, incoherent or off-topic comments will be rejected. Accordingly, ETH Zurich has already followed his proposal and elected the two Fields medal winners Martin Hairer (Imperial College London) and Akshay Venkatesh (Institute for Advanced Study Princeton) as well as the Research Director of the CNRS, Viviane Baladi, as new members of the FIM Advisory Board. At Akshays request I explained what the problem was. While mathematicians had shown that soap films are always smooth in three dimensions, Almgren proved that in four dimensions, a new kind of branching singularity can appear, making the soap films sharp in strange ways. We care about your data, and we'd like to use cookies to give you a smooth browsing experience. Technische Hochschule Zrich. Figalli has worked in the theory of optimal transport, with particular emphasis on the regularity theory of optimal transport maps and its connections to MongeAmpre equations.
