Thiago Brevidelli Garcia
Welcome to my academic home page! I’m currently a mathematics student at the M2 Research & Innovation graduate program in Toulouse, France. My main interests at the moment are representation theory, specifically Lie theory, as well as differential geometry and adjacent fields.
Stuff I wrote
- Semisimple Lie Algebras & their Representations
-
My notes on the representation theory of semisimple Lie algebras, with an emphasis in Olivier Mathieu's classification of simple weight modules (PDF)
- Global Analysis & the Banach Manifold of Class Curves
-
Riemannian Geometry course project on the manifold of class curves on a Riemannian manifold and its applications to the geodesics problem. (PDF)
- Forcing in Topos (Portuguese)
-
Set Theory course project (with Gabriel Bassan, Guilherme Sobreira and Guilherme Cerqueira) on Lawvere’s formulation of Cohen’s forcing method in the context of elementary topoi (PDF)
- An essay on the 3-sphere and some its quotients
-
Short notes on the 3-dimensional sphere, its group structure and some of its quotients by finite subgroups of its center, such as the projective space (PDF)
