Welcome to my academic home page! I’m currently a mathematics student at the M2 Research & Innovation graduate program in Toulouse, France. My main interest at the moment is the representation theory of mapping class groups. My current advisor is Maxime Wolff.
Stuff I wrote
 Semisimple Lie Algebras & their Representations

My (unfinished) 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 ${H}^{1}$ Curves

Riemannian Geometry course project on the manifold ${H}^{1}(I,M)$ of class ${H}^{1}$ curves on a Riemannian manifold $M$ 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 3sphere and some its quotients

Short notes on the 3dimensional sphere, its group structure and some of its quotients by finite subgroups of its center, such as the projective space ${\mathbb{R}\text{P}}^{3}$ (PDF)
