Large N Expansion: Vector Models

This lecture covers the Large N expansion in the context of vector models, as discussed in Coleman's book 'Aspects of Symmetry'. The slides delve into topics such as matrix models, gauge theories, and the Hooft coupling, providing insights into the generators of SUN and the adjoint of SUN. The instructor, João Miguel Penedones, presents detailed information on the matrix-valued gauge field and its significance in the expansion.
