Welcome!

Welcome to the Grav@zon - Gravity @ Amazonia - webpage! Grav@zon is a team of professors, researchers and students, dedicated to understand how gravity works and how fundamental fields/particles gravitate. The group is based mainly in Amazonia - Brazil, with collaborators in other parts of the world. Check out our team members.

Gabriel Ribeiro's Final Undergraduate Exam

Gabriel Pacheco Ribeiro defended his undergraduate monograph entitled "f(R) theories and mapping of solutions". The exam took place remotely, on 10th September 2021, using Google Meet platform, due to the pandemic COVID-19 (Coronavirus Disease 2019). The dissertation was supervised by the Grav@zon member Prof. Dr. Luís C. B. Crispino. The board of examination was composed by M. Sc. Haroldo C. D. Lima Junior (UFPA) and M. Sc. Renan B. Magalhães (UFPA). Well done, Gabriel! (September/2021)
