In memoriam: António Ferreira dos Santos
O Professor António Ferreira dos Santos nasceu em Almeirim, em 1939, e dedicou a sua vida académica ao Instituto Superior Técnico, em particular ao Departamento de Matemática. Dotado de uma notável capacidade de coordenação e liderança, colocou a sua criatividade e visão científica ao serviço da investigação desenvolvida no Departamento de Matemática.
Distinguindo-se como o melhor aluno do Liceu de Santarém em 1957, António Ferreira dos Santos obteve uma bolsa da Fundação Calouste Gulbenkian, que lhe permitiu concluir a licenciatura em Engenharia Eletrotécnica no Instituto Superior Técnico, em 1963. Em 1966, novamente com o apoio da Fundação Gulbenkian, deslocou-se para Londres, onde obteve o grau de Doutor em Engenharia Eletrotécnica pelo Imperial College, com um trabalho na área da propagação de ondas. No final da década de 80, decidiu centrar a sua atividade científica na área da Matemática. Em 1989 obteve a Agregação em Matemática. Desde então, exerceu funções como Professor Catedrático no Departamento de Matemática.
O Professor Ferreira dos Santos desempenhou diversos cargos de elevada responsabilidade académica, tendo sido Presidente do Instituto Superior Técnico entre 1978 e 1979, Presidente do Conselho Pedagógico do Instituto Superior Técnico entre 1979 e 1980, Presidente do Departamento de Matemática nos períodos de 1983 a 1984 e de 1991 a 1992, bem como Presidente do Conselho Científico do Instituto Superior Técnico nos mandatos de 2001 a 2002 e de 2003 a 2004.
Foi ainda membro de várias estruturas de gestão e coordenação do Departamento de Matemática. Esteve na criação do Mestrado em Matemática Aplicada, do qual foi coordenador entre 1983 e 1991, tendo lecionado diversas unidades curriculares, nomeadamente Análise Funcional, Análise Complexa, Operadores Lineares e Operadores Integrais.
Foi o principal fundador do Centro de Matemática Aplicada, posteriormente Centro de Matemática e Aplicações, bem como do Centro de Análise Funcional e Aplicações, do qual foi presidente até à sua jubilação, em 2009.
Criou um grupo de investigação em Teoria de Operadores, integrando-o na comunidade científica internacional. A sua investigação contribuiu de forma significativa para o desenvolvimento da teoria da fatorização e da teoria dos operadores integrais singulares, destacando-se, em particular, os seus contributos para a fatorização de funções matriciais do tipo Daniele–Khrapkov e para a fatorização em superfícies de Riemann, bem como para a análise de Fredholm de equações em intervalos compactos. Salientam-se ainda os seus trabalhos na aplicação da teoria da fatorização a sistemas integráveis e à teoria da difração de ondas. Publicou cerca de meia centena de artigos científicos e orientou várias teses de doutoramento.
O Professor Ferreira dos Santos, pela sua determinação e paixão pelo conhecimento, deu contributos de elevado nível para o desenvolvimento da investigação científica em Portugal. Para todos quantos com ele contactaram, será sempre uma referência de rigor académico, espírito democrático na relação entre colegas e permanente procura da excelência científica.

João Ribeiro wins an ERC!
João Ribeiro received a Starting Grant from the European Research Council (ERC) worth approximately €1.5 million to develop new techniques for studying channels with loss of synchronization—a particular case of communication errors where, for example, some digits may be dropped from the final message, making it difficult to compare with the initial message. Loss of synchronization errors appear in cutting-edge data storage systems, particularly in DNA data storage systems, a promising solution due to their high density and durability.

Mathematicians prove decades-old Kakeya Conjecture in major breakthrough
Hong Wang and Joshua Zahl have solved the three-dimensional Kakeya conjecture, a fundamental problem in geometry that has been open for many decades. The conjecture asks whether the space used to rotate a needle in all directions necessarily has full Hausdorff dimension. Their proof has settled this question positively in dimension three and confirmed deep ties to harmonic analysis.
First posed almost a century ago, the problem rapidly gained prominence through its linkage to other areas of mathematics. Experts hail the work as transformative, potentially unlocking progress on higher-dimensional versions and related open problems. “It’s a once-in-a-century result,” said Nets Katz of Rice University.

Historic: Mathematicians Prove the Geometric Langlands Conjecture
A team of mathematicians has achieved a major breakthrough by proving the geometric Langlands conjecture, a key part of the Langlands programme often called the "grand unified theory of mathematics." Led by Dennis Gaitsgory and Sam Raskin, the proof spans five papers and nearly 1,000 pages, and confirms deep connections between number theory, geometry, and harmonic analysis. The work, earned Gaitsgory the $3-million Breakthrough Prize.
The conjecture, first proposed in the 1980s, links algebraic geometry to representation theory through the study of Riemann surfaces. Beyond its mathematical significance, the geometric Langlands conjecture has surprising ties to physics, particularly to S-duality in gauge theories.

Students from Applied Mathematics and Computation awarded Gulbenkian Novos Talentos Scholarships
Three students from the Applied Mathematics and Computation (MAC) programme are among the eleven from Instituto Superior Técnico awarded the Gulbenkian Novos Talentos scholarships for 2025. This program, funded by the Calouste Gulbenkian Foundation, aims to support promising young talent to help them excel in their academic journeys. This achievement recognizes our students’ strong potential and commitment to mathematics.
These students will receive a valuable opportunity to engage in research projects under the supervision of our faculty. We extend our sincere congratulations to the winners and wish them every success as they continue to develop their skills and contribute to the future of applied mathematics and computation.

Ponto Fixo mathematics journal returns after 2-year hiatus
After a two-year break, Ponto Fixo, the beloved mathematics journal, is back with its fifth edition. Editor Diana Gaspar highlights that while most news would lose relevance over such a gap, mathematics remains timeless, making this edition as valuable today as it would have been in 2023. The latest issue features articles on three of the four 2022 Fields Medal winners, student contributions, and a film review. It also includes interviews with former students discussing whether to pursue a doctorate, reflecting on how advanced degrees are becoming increasingly essential beyond academia.
The journal celebrates tradition and innovation, aligning with NMATH’s newer initiatives like Time2Talk and Integration Bee. Gaspar emphasizes Ponto Fixo’s role in fostering mathematical dialogue, giving students and professors a voice, and rekindling the passion that draws people to mathematics. While aimed at math enthusiasts, the journal welcomes all curious minds, whether they’re solving puzzles, skimming, or reading cover to cover. The editor concludes by thanking contributors and reaffirming the enduring spirit of knowledge-sharing that keeps the journal alive.
