Learning outcomes

Quantum mechanics and General Relativity are two of the main pillars of modern physics. Besides of their wide range of applications in physics, they are build upon specific mathematics: functional analysis and differential geometry. This lecture aims at giving students the necessary mathematical background for their study of both theories.

Emphasis is put on concepts, tools and their articulation with physical principles like quantum superposition or relativity.

Content

The course comprises two parts: first, riemanian differential geometry and Lie groups (including articulations with classical field theory) then functional analysis (including articulation with quantum mechanics).
