Lectures by renowned scientists mark the 4th day of Mathematics Workshop in Brasília

Workshop TYAN hosts international event until this Friday with support from the World Academy of Sciences (TWAS) and SBM

Brasília (Brazil), October 6, 2023 – The fourth day of the 9th International Thematic Mathematics Workshop of The TWAS Young Affiliates Network and the 1st TYAN-Humboldt Workshop in Mathematics continued its mission of bringing together leading researchers from around the world to the stage of the University of Brasília (UnB). Scientists from Spain and Argentina were the highlight of the event organized by the Brazilian Mathematical Society (SBM) in partnership with TYAN, UnB, the Young Academy of Argentina, and the Mexican Mathematical Society.

As Chair of the first two plenary sessions of the day, Norwegian mathematician Helge Holden, from the Norwegian University of Science and Technology, welcomed the speakers. Spaniard Enrique Zuazua, from the University of Erlangen, Germany, began the work by focusing on recent results on the interaction between Control and Machine Learning. The researcher is a world leader in Partial Differential Equations and was able to share some of his knowledge about Flow Normalization with the audience at UnB.

Next, it was the turn of Celina Figueiredo, a professor at the Federal University of Rio de Janeiro (UFRJ), to take the stage to present the topic “The Computational Intractability Millennium Problem”. Currently, the researcher is a model in the studies of Graph Theory, Computational Complexity, and Algorithm Analysis, details that attracted the attention of the speakers.

In the afternoon session, Italian mathematician Pierluigi Benevieri hosted two more plenary sessions. The first was by Liliane de Almeida Maia, a PhD professor at UnB, who is a national icon in the field of Analysis, with an emphasis on Partial Differential Equations. In her time, the researcher focused specifically on talking about Classification of Radial Solutions for Nonlinear Equations.

Finally, researcher Liliana Forzani, from the Universidad Nacional del Litoral (UNL), in Argentina, closed the day with an emphasis on the Abundance x Scarcity paradox, where she delved into the exploration of regression methodologies, focusing particularly on the abundant paradigm.

At the opening of the TYAN Workshop, on Monday, she was on the discussion panel along with Márcia Barbosa, Secretary of Strategic Policies and Programs of the Ministry of Science, Technology, and Innovation (MCTI), to discuss moral harassment in academic environments, one of the main sessions of the event so far.

The exchange of knowledge from various schools of International Mathematics was approved by Fábio Tal, a professor at the Institute of Mathematics and Statistics (IME), of the University of São Paulo (USP). He was one of dozens of professionals who exhibited samples of their work in Brasília and is impressed with the range of references in various specialized areas.

“The TYAN Workshop had presentations of excellent scientific contributions, from an impressive range of areas of mathematics. From algebra to mathematics more directly linked to applications. And global integration is always very relevant. Brazilian mathematics has only become one of the best in the world because it has all these international connections, because it is exposed to new ideas and techniques as soon as they are developed. This allows us to absorb them early on and also allows for greater exposure of our work,” Tal assesses.

Master’s student Maxmilian Siqueira, from the Federal University of Alagoas (UFAL), is totally in line with this. The four days of the TYAN Workshop have already given him different guidelines on how to follow his academic research line.

“Having the opportunity to have come to an event like this is very rewarding, because I can expose my work to other people, often references from other countries in Latin America, even from other continents. And obviously it makes me see different ways of doing mathematics from the one I am used to in Alagoas,” he highlights.

The program at UnB runs until this Friday and will feature more plenary lectures by leading names in world mathematics, panels, and the continuation of special sessions.
