- From January 5 to 7, the event was held, co-organized by UC, USACh, and the CMM of the University of Chile..
During the first week of January, FisMat Days 2026 took place, an event co-organized by the Center for Mathematical Modeling (CMM) at the University of Chile.
This scientific meeting was held at Ruka Afunalhue and brought together researchers and students from institutions in Chile, Colombia, and France.
The talks presented recent advances in the spectral theory of Schrödinger and Dirac operators, topological and random aspects, and their connections with the physics of quantum and relativistic systems.

Prof. Vincent Bruneau from the University of Bordeaux teaching his mini-course on Spectral Shift Function.
The speakers at the meeting were:
- Fabián Belmonte, U. Católica del Norte
- Vincent Bruneau, U. de Bordeaux
- Giuseppe De Nittis, Pontificia U. Católica de Chile
- Cristián Figueroa, U. de Santiago de Chile
- Loïc Le Treust, U. Aix-Marseille
- Javier Lorca, U. de La Frontera
- Pablo Miranda, U. de Santiago de Chile
- Gregorio Moreno, Pontificia U. Católica de Chile
- Luis Felipe Núñez, Pontificia U. Católica de Chile – UC
- Daniel Parra, U. de La Frontera
- Andrés Reyes, U. de Los Andes (Colombia)
- Dominique Spehner, U. de Concepción
The event also included a course led by Professor Vincent Bruneau, who gave an introduction to the Spectral Shift Function, which was greatly appreciated by the graduate students who participated.

Talk by Leila Reyes Giménez, student in the Master’s Program in Applied Mathematics at the University of Chile.
Meanwhile, the organizing committee was formed by Marouane Assal from the University of Santiago de Chile, Amal Taarabt from the Catholic University of Chile, and Hanne Van Den Bosch, principal investigator at the CMM, who emphasized that this event “is a valuable opportunity to maintain ties with researchers from various regions in Chile and encourage a new generation of students to conduct research in this area.”
This event was funded by the Center for Mathematical Modeling through its ANID FB210005 Basal Project.
