It is our pleasure to announce the next Ghent Methusalem Microlocal Day # 12, which will take place on Tuesday, 8 April 2025.
The Microlocal Day is an event featuring a brief and intensive series of lectures on various aspects of microlocal analysis and related topics. The program consists of both research presentations and survey lectures intended for researchers and PhD students interested in the field.
Venue: Leslokaal 3.1, Campus Sterre, S8, Ghent University, Belgium
Schedule: all times CEST
Opening 11:00-11:05
11:05-11:50. Sergo Yepiskoposyan (National Polytechnic University of Armenia, Armenia)
Title: Orthonormal Systems and Greedy Algorithms
Abstract: The lecture will present classical orthonormal systems such as Rademacher, Walsh, Haar, Christenson-Levy systems and their properties. As well as greedy algorithms for these systems. Convergence results of the greedy algorithm for the Walsh system in the spaces $L^1[0,1)$ and $L_{\mu}^1[0,1)$ will be presented.
14:00-14:45. Sergo Yepiskoposyan (continuation)
15:00-15:30. Bolys Sabitbek (Queen Mary University of London, UK)
Title: Critically degenerate/singular hyperbolic equations
Abstract: We will discuss the wave equations that becomes weakly hyperbolic and singular at time t = 0. We provide precise quantifications for the asymptotics of solutions as t approaches 0, the scattering problem and the loss of regularity caused by the degeneracies at t = 0.
15:40-16:00. Aidyn Kassymov (Institute of Mathematics and Mathematical Modelling, Kazakhstan):
Title: On fractional inequalities on metric measure spaces with polar decomposition
Abstract: In this paper, we prove the fractional Hardy inequality on polarisable metric measure spaces. The integral Hardy inequality for 1<p≤q<∞ is playing a key role in the proof. Moreover, we also prove the fractional Hardy-Sobolev type inequality on metric measure spaces. In addition, logarithmic Hardy-Sobolev and fractional Nash type inequalities on metric measure spaces are presented. In addition, we present applications on homogeneous groups and on the Heisenberg group. (joint paper with M. Ruzhansky and G. Zaur).
16:00 – Closing.
This Microlocal Day continues the tradition of Microlocal Days that we have been organising at Imperial College London, then continued at Ghent University. So, this Microlocal Day can be viewed as Microlocal Day #12.

Topic: A brief introduction to modulation spaces on the Heisenberg group
Time: Thursday, 3rd April, 2 PM – 4 PM CEST
Friday, 4th April, 10 AM – 12 PM CEST
Where: Leslokaal 3.1 (Krijgslaan 281, Building S8, Ghent University)
The lecture begins with a review of the definition of modulation spaces on R^n, reformulated using the Bargmann transform. It then introduces twisted modulation spaces through the twisted Bargmann transform. Finally, modulation spaces on the Heisenberg group are presented as direct integrals of twisted modulation spaces. The lecture concludes with a discussion of some fundamental properties of these spaces.

Topic: Every classical inequality for the Fourier operator is trivial
Time: Thursday, April 3rd, 11:00 AM-12:30 PM CEST
Where: Leslokaal 3.2 (Krijgslaan 281, Building S8, Ghent University)
In this talk, we will see that if the Fourier operator is bounded between two classical spaces (for instance, rearrangement invariant spaces), then every operator that maps L1 and L2 to Linfty and L2, respectively, must also be bounded. We will also discuss why this means that there cannot be any “interesting” classical Fourier inequalities and give some applications. This is joint work with Sergey Tikhonov.

We are thrilled to announce that André Pedroso Kowacs has successfully defended his PhD dissertation jointly at Ghent University and Universidade Federal do Paraná, under the supervision of Profs Alexandre Kirilov and Michael Ruzhansky! 🌟
André began his academic journey with a Bachelor’s degree in Mathematics from UFPR in 2019. He quickly moved forward, embarking on his PhD directly in 2020, and spent 10 months in Belgium working on a joint PhD at our Ghent Analysis and PDE center of Ghent University. His research interests have focused primarily on analysis and partial differential equations, particularly in the context of compact Lie groups. 🌐🔍
His dissertation, titled “Links between regularity and inequalities on compact Lie groups”, presents remarkable results, including:
This is a major achievement in the field of mathematics, contributing significantly to our understanding of the intricate connections between regularity and inequalities on compact Lie groups. 💡✨
Throughout his academic career, André has been actively involved in the Linear Equations group and the Universal CNPq projects since 2019. His work has resulted in two published papers and six preprints on arXiv. 📚🎓
Congratulations again to André, on this monumental achievement! 👏 👏👏
We are excited to see all the great things he will accomplish in his future endeavors and wish him all the best in his continued journey of academic and professional excellence. 🥳🎉🎊
