Sebastian Schlegel Mejia

Sebastian Schlegel Mejia is a Lecturer at the School of Basic Sciences (SB) of École Polytechnique Fédérale de Lausanne (EPFL), affiliated with the Department of Mathematics. He teaches courses on algebraic geometry, including "Algebraic Geometry III - Selected Topics" (MATH-535), and contributes to research via his role at the Chair of Arithmetic Geometry (ARG).

Research Interests

His research focuses on algebraic geometry, category theory, and mathematical physics. He explores connections between BPS algebras, generalized Kac-Moody algebras, and 2-Calabi-Yau categories, alongside applications in nonabelian Hodge theory, moduli spaces of Higgs bundles, and stacks. His work bridges theoretical mathematics with quantum field theory.

Publications Trends

Recent articles emphasize BPS algebras, cohomology in Calabi-Yau categories, and their implications for nonabelian Hodge theory and moduli spaces. Key themes include the interplay between algebraic structures, geometric frameworks, and mathematical physics.
