Stefan Fredenhagen
My research deals with theoretical and mathematical questions in field theory, gravity and generalisations thereof, in particular I am interested in higher-spin gravities and conformal field theories. Higher-spin gravities generalise ordinary gauge theories like Yang-Mills theory or general relativity by fields of higher spins. They show an interesting relation to conformal field theories with global higher-spin charges via holography — for an introduction in the context of 3-dimensional higher-spin gravity, see our recent lecture notes.
