30 de junho a 4 de julho de 2025IMPA, Rio de Janeiro, Brazil
Fourier Analysis & Beyond I
We are glad to announce the the workshop “Fourier Analysis & Beyond”. The event is meant to present the young community to some of the topics in the interface of Fourier analysis and other areas, and bring together specialists to present their recent contributions and stimulate new directions of research.
The first edition of the workshop will take place at IMPA, with 3 mini-courses and invited talks. We will also have space for contributed talks and posters.

Financial Support
The Organizing Committee is dedicated to finding resources to offer financial support to students and early career researchers. However, we encourage those who can to use their bench fees or project resources to do so. For those applying for support you must attach a short CV in pdf format on the registration form. There will also be space for poster presentations. In this case, in addition, please provide an abstract in the registration form. The deadline is February 28th and the selected candidates will be notified shortly after.
Tourist Information
Hotel Information
The best way is to look for a hotel on the website: booking.com
And add a filter of neighborhoods: Ipanema, Leblon, Copacabana.
Also, there is one hotel in Botafogo: Ibis Rio de Janeiro Botafogo.
Invited speakers will be allocated in the Hotel Vermont.
The best way to come to IMPA is by cab or uber.
IMPA is located in the yellow circle and hotels in the red circle. (booking.com)
