Project of Scientific Cooperation Belgium-Brazil.

It is our pleasure to announce that the Ghent Analysis and PDE Center has been awarded one of the Global Minds Fund (GMF) International Grants for 2025, funded by the Research Department at Ghent University. This initiative aims to address global challenges through innovative research and dynamic collaboration. We recall that is our second successful global minds cooperation project (visit the website of our Global Minds Project 2025 here!).

Since 2017, the Federal Government allocates funds, through the office of VLIR-UOS, to the Global Minds Fund (GMF) of Ghent University. GMF operates as driver of change for sustainable development, by producing and valorising relevant knowledge and expertise through mutually beneficial partnerships.

The idea is to cooperate with several key figures of Brazilian mathematicians on a project leading to educational advancement in Brazil. This project will be valuable to pass to younger generations a significant perspective in the field of partial differential equations and control theory through the leading Brazilian partners of the project.

The project is promoted by Prof. Dr. Michael Ruzhansky (PI) and co-promoted by our FWO Postdoctoral Researchers (Co-PIs) Dr. Duvan Cardona and Dr. Marianna Chatzakou. As part of our strategic alliances we will cooperate with ICMAM Latin America (International Community of Mathematicians from Latin America) in the organisation of several virtual conferences related to this project.

   (International Community of Mathematicians from Latin America). The organisation of these
   conferences will be supervised by the co-promotor Dr. Duván Cardona.
   
2. Editorial Project: These two conferences will receive scientific contributions from outstanding participants and speakers collected in the book:
   
   Analysis and PDE in Latin America 2025, Global Minds – ICMAM 2025,
   
   and will be submitted to the Book Series of the Ghent Analysis and PDE Center: Research Perspectives Ghent Analysis and PDE Center, Springer-Birkhäuser.
   
   
3. In-person Workshop. From April 27th to 30th 2026 (tentative schedule), the workshop:
   
   Global Minds in Partial Differential Equations and Control Theory
   
   will take place in person at Ghent University at the facilities of the Ghent Analysis and PDE Center.

Joint lecture topic: Analysis of a Class of Degenerating Operators and Their Spectra: Multiscale-type Approximations

Abstract

Homogenization theory establishes that uniformly elliptic operators with rapidly oscillating periodic coefficients have operators with constant coefficients as their appropriate limits. One approach is based on applying a (scaled) Floquet-Bloch-Gelfand transform to the resolvent problem in $\mathbb{R}^n$ and then constructing uniform approximations near a singular point of the quasi-periodicity parameter. This becomes much more subtle if the coefficients are asymptotically degenerating, and the limit operator appears to be a “two-scale” one with a band-gap limit spectrum. There are diverse examples of PDE and other models displaying similar features. In this minicourse, based on [1], we review the background and introduce an abstract scheme allowing to construct such approximations for a wide class of asymptotically degenerating operators and their spectra. This is accompanied by error bounds, and illustrated this by various examples. In particular, a key example of high-contrast PDE models displays surprising links to signal processing via a novel $L^2$-isometric two-scale interpolation operator of Whittaker-Shannon type.
