Geometry in Algebra, Algebra in Geometry
We are happy to announce the 8th edition of the workshop "Geometry in Algebra, Algebra in Geometry", an event whose aim is to bring together researchers and postgraduate students with interests at the interface between geometry and algebra, to foster the exchange of ideas, discuss recent contributions, and open new research avenues. The workshop program will include 3 minicourses, invited lectures and a poster session.
Registration
| Category Price | Until August 22nd, 2025 | From August 23rd, 2025 |
| IMPA´s Students | R$ 30,00 | R$ 50,00 |
| Students (Master and Ph.D) | R$ 80,00 | R$ 120,00 |

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. The deadline is July 31st and the selected candidates will be notified shortly after.

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.
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)
*Official hotels and agencies are not allowed to make contact with participants (unless they, the participant, has themself initiated contact with the hotel). If you have received a message from Global Travel Experts it is not from the organization of the event, and probably a scam. All official messages about the event will be sent from the e-mail eventos@impa.br.*
