Biography:
Emanuel Mendonca Viana is a mathematician working in Differential Geometry and Geometric Analysis. He earned his degree in Mathematics from the Federal University of Ceara, where he also engages in teaching and research. His work focuses on curvature-driven variational problems,critical metrics,and global properties of Riemannian manifolds. He has participated in advanced research programs, including the IMPA Summer Postdoctoral Program, and collaborates with specialists in geometric PDEs and related fields. His contributions advance the analytical understanding of geometric structures in modern Riemannian theory.
